Improve auto calibration with a knowledge of the past offsets of a dongle #6

Improve auto calibration with a knowledge of the past offsets of a dongle.

Perhaps use the serial number. It will have to be programmed. Some dongles don't have that capability.

At least during the current run of rtl_hpsdr a database of the most common calibration offsets can be maintained and if the current calibration returns a value that is far off from the most common offset, ignore it.

I just added some more constraints on when to change offset in calibration. It basically removes the jitter when the FFT is bouncing between two adjacent bins.

BTW, I mistakenly checked in my binaries in cusdrk, can you revert anything I put in there today?

The binary cusdr should be removed now.
