Subject: [PATCH] feat: add fzf functions to interact with git worktrees

These have to be functions sadly because `cd` doesn't work otherwise.
This just means there is more reason to have subcommand aliases on a shell level. :)

Heavily based on nerdypeppers stuff[https://peppe.rs/posts/curing_a_case_of_git-UX/].
