feat(extras): adding telescope-frecency
* telescope-frecency is an alternative for the telescope.oldfiles picker * fully customizable via opts.integration.frecency and opts.extensions.frecency (telescope config) * gimmick: press "[" (opts.lhs_switch_to) to jump from frecency to oldfiles and vice versa * use `opts.integration.frecency.enable_oldfiles_mappings = true`, to remap the default oldfiles mapping too.
