Switching to soapy? (LimeSDR support)

Any chance of a easy change to use soapy or in some way support using the LimeSDR for this? I think the gr-osmocom works as well. I've never dived into python but I assume this isn't too difficult a change?

Note that switching source.py's args= line to "soapy=0,driver=lime" is enough, but I'm uncertain how that should be integrate properly for a command line switch.
