Experiment with a 100ms timeout on ESC

@lhecker While I think a longer timeout is preferable for key parsing anyway, note that the problem in issue #243 could be solved more reliably by removing the timeout altogether in the setup_terminal method here:

edit/src/bin/edit/main.rs

Line 533 in db1e813

let Some(input) = sys::read_stdin(&scratch, vt_parser.read_timeout()) else {

By that I mean an infinite timeout, or at least something like a couple of seconds if you want to be really safe. Because you're assumedly not dealing with keypresses where you need to recognise a solitary escape. Everything you receive at that point should be a full escape sequence.

Oh, that's a good idea! Thank you for that!
