Remove git dependencies

[Speak2Erase]

Git dependencies prevent us from being able to publish to crates.io (if we want to) and are also inherently unstable. Most of our git dependencies are for pull requests that haven't been merged yet (i.e. flume, cpal) or crates that haven't been updated on crates.io yet (catpuccin-egui).

The only exception to this is wezterm-term, which we use to handle most of the terminal functionality. We aren't really supposed to be using wezterm-term anyway, as it's a crate tailor made for wezterm and has no stability guarantees.
