What

This TBD PR attempts to normalise all python code to idiomatic, Python 3.8 compatible, syntax, primarily around typing ((through from __future__ import annotations), but also other aspect covered by PyUpgrade such as f-strings, etc.

This has wide ranging impact on the Python code, so could potentially mess-up existing PR.

TBD:

  • remove set -e from py-lint (annoying when errors are triggered by out-of-PR files, but impacts CI)
    • My take: leave as is. It's annoying when lints dont pass (as was the case as of ~ 370e16f), but this shouldn't be the norm.
  • from __future__ import annotations was "manually" added, so it's not done by py-format nor checked by py-lint.
    • My take: ok as is, but let's make it a concession to always add from __future__ import annotations in python files.

OMG, the type annotations are so much nicer with |!

We could consider checking that each .py file contains from __future__ import annotations in our own lint.py if we want to.

Actually, Ruff appears to have something like that already: astral-sh/ruff#1762

I'll try and add that.

This can wait for a follow-up PR imo; I'd rather we merge this before monday kicks in, this is a ticking merge conflict bomb 😬

Convert objectron proto.py back to using typing.List (#2559)
d21fefa 
### What

The change from List -> list was introduced as part of:
 - #2361
 
However it seems to break objectron on python3.8:
 - #2557

Reverting just this bit causes it to work for me, though I don't fully
understand the intention or ramifications.

Exclude from objectron/proto/objectron/proto.py from `just py-forma…
bb8e0e9 
…t` (#2562)

### What

For some reason, `objectron/proto/objectron/proto.py` relies on
old-style annotation, so it broke with #2361 and was subsequently fixed
by #2559. `just py-format` insist on reverting that latest fix, so the
file is explicitly excluded from `pyupgrade`. I used a pretty ugly hack
because `pyupgrade` is [way too
opinionated](asottile/pyupgrade#809) to even
accept comment-based disabling.

Release 0.8 - Infrastructure investments and more transform improveme…
df05f49 
…nts - 2023-07-27 (#2842)

## [0.8.0](v0.7.0...v0.8.0) -
Infrastructure investments and more transform improvements - 2023-07-27

[Rerun](https://www.rerun.io/) is an easy-to-use visualization toolbox
for computer vision and robotics.

* Python: `pip install rerun-sdk`
* Rust: `cargo add rerun` and `cargo install rerun-cli`
* Online demo: <https://demo.rerun.io/version/0.8.0/>


### Overview & Highlights
- `log_pinhole` is now easier to use in simple cases and supports
non-RDF camera coordinates.
[#2614](#2614)
- You only need to set focal length and optional principal point instead
of setting the full 3x3 matrix.
- There is also a new argument: `camera_xyz` for setting the coordinate
system. The default is RDF (the old
default). This affects the visible camera frustum, how rays are
projected when hovering a 2D image, and how depth
   clouds are projected.
- The visualizer can now show coordinate arrows for all affine
transforms within the view.
[#2577](#2577)
- Linestrips and oriented bounding boxes can now be logged via batch
APIs in python.
- See: `log_linestrips_2d`, `log_linestrips_3d`,
[#2822](#2822) and `log_obbs`
[#2823](#2823)
- Rust users that build their own Viewer applications can now add fully
custom Space Views. Find more information
[here](https://www.rerun.io/docs/howto/extend-ui#custom-space-views-classes).
- New optional `flush_timeout` specifies how long Rerun will wait if a
TCP stream is disconnected during a flush.
[#2821](#2821)
- In Rust, `RecordingStream::connect` now requires `flush_timeout`
specified as an `Option<Duration>`.
- To keep default behavior, this can be specified using the
`rerun::default_flush_time()` helper.
- In Python `flush_init_sec` is now an optional argument to
`rr.connect()`
- In Rust, the `RecordingStream` now offers a stateful time API, similar
to the Python APIs. [#2506](#2506)
- You can now call `set_time_sequence`, `set_time_seconds`, and
`set_time_nanos` directly on the `RecordingStream`,
     which will set the time for all subsequent logs using that stream.
- This can be used as an alternative to the the previous
`MsgSender::with_time` APIs.
- The Rerun SDK now defaults to 8ms long microbatches instead of 50ms.
This makes the default behavior more suitable
for use-cases like real-time video feeds.
[#2220](#2220)
- Check out [the microbatching
docs](https://www.rerun.io/docs/reference/sdk-micro-batching) for more
information
   on fine-tuning the micro-batching behavior.
- The web viewer now incremental loads `.rrd` files when streaming over
HTTP. [#2412](#2412)

![Open Photogrammetry
Preview](https://static.rerun.io/9fa26e73a197690e0403cd35f29e31c2941dea36_release_080_photogrammetry_full.png)

### Ongoing Refactors
- There have been a number of significant internal changes going on
during this release with little visible impact.
This work will land across future releases, but is highlighted here
since much of it is visible through the
   changelog.
- The layout of the Viewer is now controlled by a Blueprint datastore.
In the future this will allow for direct API
control of the layout and configuration of the Viewer. A very early
prototype of this functionality is available
    via the `rerun.experimental` module in Python.
- An entirely new code-generation framework has been brought online for
Rust, Python and C++. This will eventually enable
new object-centric APIs with a more scalable, consistent, and ergonomic
experience.
- Bringup of C++ support is now underway and will eventually become our
third officially supported SDK language.

### Known Regressions
- Due to the Blueprint storage migration, blueprint persistence on web
is currently broken. Will be resolved in:
