feat(fzf): add fzf-lua support in Readme & add TodoFzfLua command (#312)

## Description

<!-- Describe the big picture of your changes to communicate to the
maintainers
  why we should accept this pull request. -->

This plugin has support `fzf-lua` ( an alternative to `Telescope` ) in
lua/fzf.lua. But nowhere in the `README` it is said that there's
`fzf-lua` support, so i added it explicitly in the `README`. There's
also no commands to call the function so i added the `TodoFzfLua`
command
