Support fuzzy search directly in SubRPC

[PierreBesson]

In the README, we have the suggestion to integrate subrpc with fuzzy search provided by fzf.

Skim is an fzf alternative written in Rust that support using it as a library. By using the Skim library directly in SubRPC, it would be possible to provide features similar to the sub shell function without using an external program such as fzf.

Thanks for the issue @PierreBesson. I think it is healty to keep tools doing their job and not doing too much but I see your point and that is something that may be added as optional feature.

It is not yet clear to me what the effort vs features ratio will be between subrpc+skimlib vs piping to fzf vs piping to skim. I also never played with skim so I will check it out and in any case, I could add an example similar to the fxf function but using skim as a start.

Especially, using fzf means your are piping and also can use tons of other tools such as grep, uniq, sort, etc...
in a way that solve each users' problem.

To be a good alternative means implementing all those options as well...

Are there use cases you have in mind that could be done integrating the skim lib into subrpc that is not available when piping to fzf or even skim itself ?
