Dimitri Stolnikov ccff99ea4f uhd: add lo_offset argument
This might be used to tune away from the noisy center region caused by

Use case:

print "\nSupported rates:"
for rate in self.osmosdr_source_c_0.get_sample_rates():
	print rate.start()

print "\nSupported gains:"
for gain in self.osmosdr_source_c_0.get_gain_range():
