Adds xsel support

[jgarte]

Hi, this is a WIP pr for adding xsel support as a configuration option.

Any help or guidance is much appreciated.

@jgarte I guess the expected behavior is to check if xclip is in the PATH otherwise fall back to xsel? You could use the which crate to do this or traverse the PATH and check (e.g this SO answer)

Cool, I'll check that out.

This is how emacs-xclip does it:

Sounds like the which crate might be the way to go. Thanks for sharing.

It would be really cool if those two constants will be available for override in config. In my case I need wl-copy on Wayland.
