Exposing named nord colors

[Felipe Seré]

👋 I'm a huge Nord and shaunsingh/nord.nvim fan, so thank you for this repo and the hard work.

Would it be possible to expose the values of the nord colors with their names?
I'm setting up the colors for nvim-cmp and it would be easier for me to write

highlight! CmpItemAbbrDeprecated guibg=NONE gui=strikethrough guifg=nord.lightest_gray
" and..
highlight! CmpItemAbbrMatch guibg=NONE guifg=nord.deep_blue
" and ...
highlight! CmpItemKindInterface guibg=NONE guifg=nord.green

That reads nicer than using nord1 etc.
I'm happy pull up a PR if this is something you'd accept.
