William Carroll c17796a60d Rename alist.el to al.el
After switching my namespace separator from "/" to "-" the function,
`alist-get`, clashed (surprise!) with the pre-existing function, `alist-get`. As
I was struggling to debug my broken Emacs (it broke bc Emacs 27 rolled out), and
I changed the module name, "alist", to "al" attempting to defuse the issue.
