Add getScanOutputRange() to read outputRange data from the LMS1xx.
Use output range query for min & max angles, num_values, and time_increment.

Previously, the code would query the LMS1xx for its capabilities, which
might exceed its current configuration (in terms of angle range).  Now, we
query the LMS1xx for its configuration when setting scan parameters such
as min & max angle, number of values reported, and time increment.
Remove (some) commented out debug code.
Merge pull request #2 from wpd/master

Use LMS1xx reported configuration instead of capabilities for angle_min, max, etc...
