Long Build Times

[martinmortsell]

The new way the pacs are generated leads to a noticable increase in build time. A quick test on my laptop gave me 4:15 with the new pacs and 2:49 with the old ones. EDIT: building the HAL, that is.

It seems the main difference is that only the SVDs and build.rs is published to crates.io, and not the actual source code.
Is there a reason for this?
To me it feels like you might as well generate the full source before publishing, which should bring compile times down to what they were before.

GitHub is notoriously bad at handling so many files, so this guarantees PRs aren't broken. My build times are better, but I mostly use multicore machines. And they shouldn't rebuild.

Second argument is that svd2rust now has extra features, like generics or atomics; in this user-side model we can turn them on and off.

To speed up builds I suggest having sscache up and running.
