This code seems to calibrate I/Q phase and gain during the
device initialization.
This is done only once, and it doesn't seem to be needed to

This tuner works with 2 modes: automatic gain mode and manual
gain mode. Put it into automatic mode, as we currently don't
have any API for manual gain adjustment.
The logic to allow setting the manual mode is there, as it is
just a few extra code. This way, if/when we latter add support

The rtl-sdr library disabled IMR callibration. While I'm not sure

- If rtl-sdr disabled it, perha
