Hi. Thanks for this great project. I wanted to ask if we could get an official solution to register links with any format.

Like https://github.com/LabhanshAgrawal/xterm-link-provider but... official 😅 The problem with that project is that it's not updated anymore, it uses an old Xtermjs version and it has some issues when handling line breaks & emojis (which I attempt to solve in that PR) but also incompatibilities with addon-fit (like links not formatting well if they end in the last character of a line).

I ask primarily because maybe you have a more generic solution working and it'd be a matter of just exposing it. I think a lot of users will find it useful!
