neovim will block/freeze when retrieving lots of candidates

[FelipeLema]

hey, everyone

this is about the only problem I've encountered with this plugin. I take my hat off and congratulate the maintainers on some real robust code you have here.

So I have a single directory with about 1500 files and the whole neovim will freeze and not accept any inputs until all candidates have been fetched. It takes a few seconds to regain control of neovim.

My advice is replacing the while true block that does fs_scandir_next() and instead execute it in a separate thread using something like luv's thread pool work scheduling, probable with some sort of short-circuiting feature.

I can do a PR for this if the maintainers accept that this is within the scope of this package/plugin
