feat: resume last picker

[calebdw]

Hello!

One of the things that I rely heavily on from telescope is the ability to resume the last picker (require('telescope.builtin').resume) --- this is a life saver.

Could a similar feature be added here?

Thanks!

Adding to this, I see we can open the picker and cycle the history back (default keymap is <C-up>), however this doesn't include pickers that were closed without a file being selected.

It would be really nice to have a way to resume the last query without having to open the picker again, and also if no files were selected.

PR #438 (#438) implements requested resume feature. Saves picker state before close (query, results, cursor, pagination). Restores via :FFFResume or require('fff').resume(). Mode-specific resume available: find_files({ resume = true }), live_grep({ resume = true }) with fallback to new picker if no saved state.
