Implement Gain

[cjcliffe]

• VGA, MIXER, LNA
• LINEARITY, SENSITIVITY?

It would be really great if you can implement general gain setting in both "linearity" and "sensitivity" mode. E.g. "linearity" mode is very useful for spectrum analyzer apps (like my QSpectrumAnalyzer). I can reimplement it in app by taking gain tables for linearity and sensitivity mode from https://github.com/airspy/host/blob/master/libairspy/src/airspy.c#L117 and setting VGA, MIXER, LNA gains manually according to it, but it seems wrong duplicating it like this. It should be in lower level.

I'm still very interested in this, it appears I cannot pass the values from the lookup table properly by hand.
