True Color (24-bit) and italics with alacritty + tmux + vim (neovim)

This should make True Color (24-bit) and italics work in your tmux session and vim/neovim when using Alacritty (and should be compatible with any other terminal emulator, including Kitty).

Testing colors

Running this script should look the same in tmux as without.

A formatting comparison.

How will the two tools format the following input code:

export const f = function(a) { if (a === 0) { return []; } return [1,2,3,4,a].map(int => int * 2); }
