Use skim instead of fzf

[jtrv]

Can you add support or a config option to add the rust implemented fuzzy finder "skim"? I believe it uses the same flags and syntax.

ok, i need to work on this :)

skim is also usable as a library crate, which means you could just build it into sad without needing it to be installed separately.

(Please don't remove support for fzf.)

I think can just fallback to skim if fzf is not installed since skim can be used to replace fzf.

[ssokolow]

What if we have fzf installed for something that only supports it, but we prefer skim where supported? There should be an option for that.

(eg. so in-process operation can result in improved I/O access patterns to load skim compared to fzf.)
