Implementing remove_dc like Airspy's iqconverter_int16 and iqconverter_float?

[ghostop14]

Hi folks,

Any chance libhackrf can get a built-in remove_dc function like that integrated into libairspy? (See https://github.com/airspy/host/blob/master/libairspy/src/iqconverter_int16.c and iqconverter_float.c). I get doing offset tuning, but for large bandwidth applications where you can't tune it out of the range you want, it takes away from the value of that great 20 Msps range.

Thanks!
