Investigate Mise

[kytta]

mise is quite a nice replacement for pyenv, asdf, etc., as well as direnv and task runners. It has the ability to run script tasks which define:

• sources (don't run if the sources did not change)
• outputs (don't run if output exists)
• env (just useful)
• dependencies (run in parallel)

It also supports test grouping, which is nice.

I do not plan to replace/compete with mise, but I want to take some of those features into skyr. Maybe even make it mise-compatible, who knows. For now, I don't see a way to change the mise tasks folder, though.
