Added nix LSP (nil_ls)

I love it, it just works out of the box, unlike nixd which was so broken
I couldn't get it to work, and it's so much more featureful, it has
insane autocompletion for keywords and vars and I can go to
definition/go to references on files/vars etc and it has diagnostics and
shows when there is an error, it's so much better, and it has completion
for nix options
