Support for ligatures

[rm-dr]

I don't know if this is a ttyd or vhs problem...

But it would be awesome if vhs supported programmer ligatures in its recordings (like those in nerd fonts)

Hey this is a good idea! I believe xterm.js does support ligatures, but we should make this feature opt-in:

Set Ligatures enabled # or
Set Ligatures on

Does xterm.js support ligatures?

Seems some work has been done here, but I haven't found a way to use them in ttyd.

Not sure how to include add-ons with xterm canvas and with how we're using it in VHS, but here's some info that might be helpful
