Consider flake-parts compat

[yangm97]

I really like FUP but right now it stands as a big monolith which requires a full buy-in.
Splitting functionality into a set of flake-parts modules might be desired.

Context: I'm rewriting my config to use flake-parts because it became a tangled mess (my fault) but I'd like to keep using FUP to some extent i.e. the repl command.

Tell me something, what else do you like about fup?

For a while, I was thinking of deprecating fup in favor of flake-parts since it is a great project, but it involves more stuff than just moving things out from my side
