The core used does not support RadioHead, this is the go-to library for using the cheap green 433MHz chips from China so this would be awesome to have!
Best option:
Better cores for the tiny, like this one
Second best option:
Enable digispark-tiny to use Arduino as ISP
Not so great solution:
Change current ATtiny core so RadioHead compiles

Bonus points: Simple solition for adding my own core, as described here: https://github.com/SpenceKonde/ATTinyCore/issues/124
