scriptscrub (`script` output pruner / watcher)

Edit 2024-01-26: I ended up feature creeping it a bit. It can now be used as a less input filter, and asciinema-esque recording playback.

A less bad name TBD.

This is a little program I made to convert script captures into properly laid out text. A lot of the behaviour still isn't quite right, but I'm pretty happy with it as a proof-of-concept.
