ttyd support

[skalien]

Is your feature request related to a problem? Please describe.
It is not related to any problem in hyper.js. It is just that there are no apps that can connect to a server that exposes a ttyd terminal session through an open port. And hyper.js seems to be the perfect app to implement it because it is based on xterm.js

Describe the solution you'd like
I want hyper.js to be able to connect to a ttyd terminal session hosted on a server.

Describe alternatives you've considered
Tried almost all other apps. None supports it.

Additional context
None.
