Add support for vt102 "Scrolling region"
I'm currently using your library for a personal project (MUD client). However I still need to send a lot of manual escape data to be able to handle scrolling regions (Think, input area at bottom of terminal (10%) and scrolling 'mud' output at the top 90%).
It would be sweet if this could be handled through termion and "obscure" all my escape code logic within termion calls.
I have implemented a solution for this already. Just need to test and confirm. I just wanted to create the issue to keep things orderly and also check if it's even in your interest to add it.
