Ability to select custom language for a file

[dakyskye]

What do you want

Either a way to define file names in NVim config and custom asset names, or a new command, that will save what language you want to be displayed for a certain file in the program memory. Or maybe both way.

Why

I was editing a shell script file, that has no file extension. I'd like others to see what language I am writing in that file.

Implementation hints

For the command, save the exact file path to memory, and iterate over this new array before the original languages array.
For config, just simple Vim syntax:

let g:cord_custom_types = {
    \ 'mySpecialFileName' : 'shell',
   \ 'mySpecialFileName.with.a.file.extension': 'powershell'
\ }

Possibly this should rather go in coc-settings.json than in actual nvim config
