Record and share successions of blocks

Is your feature request related to a problem? Please describe.
Sharing blocks is cool but limited and very static, asciinema is awesome and there is a real opportunity to integrate something similar in Warp and make it awesome.

Describe the solution you'd like
A better integrated version of https://asciinema.org/, that supports blocks. You could start recording a terminal session that will record the IO while preserving blocks. You can then share it just like you can currently share a block, the webpage would then play the session gradually revealing input and outputs of successive blocks. That could be very powerful when paired up with a button on the webpage to directly execute the session in Warp (mentioned in #54): you could not only easily share but also execute entire scripts. That can be great when following tutorials / walkthroughs where you have to repeat commands.

@simjnd Thanks for the suggestion! I think this dovetails nicely with our planned work on shared sessions, we'll definitely need to think about these use-cases as well!

The education space could really benefit from some similar thought.

For instance, it would be nice if 1+ blocks were exportable/embeddable in some way that allowed developers to intermix it with a written tutorial. Then as they read the tutorial, clicking any embedded block could open up the warp app and insert the text making it easy for users to tweak and hit enter.

It could also be a nice marketing opportunity if a bunch of write-ups start using embeds that advertise Warp.
