New source: nvim-cmp-vlime

[HiPhish]

I have created a new source: nvim-cmp-vlime. It provides Common Lisp completions using the Vlime plugin, which is similar to Slime for Emacs.

Common Lisp is a bit weird as a language. It is very dynamic, so the way you write Lisp code is that your start a Lisp interpreter, load your project into the running image, and then as you write new code you send it over to the running Lisp process for evaluation. In a way this is similar to LSP where we also need to communicate with a remote process to get results, except that you need to send code over manually because it cannot be in an incomplete state like it can be in LSP.
