mmirs_qrp: python 3 compatibility

[astrochun]

Some basic fixes where implemented to work with python 3.

The first is removing one print statement. Another is integer vs float for i_sky. Finally, yaml may not be installed, so I included a try/except to handle this. However, when I ran it through with py3, I got the following information dump:
