(Request) Possibly support new bladeRF features

[alphafox02]

I was thinking how best to go about trying to get Soapy to account for changes Nuand made to gr-osmosdr. I suppose the best route would be for Soapy bladeRF to account for changes, but perhaps this SoapyOsmo may present an easy way for the time being.

Have a look here,
https://github.com/Nuand/gr-osmosdr

The last few commits enable a feature called, I believe, oversample or something of that nature. In this mode, it's reduced to an 8bit sample but it allows the bladeRF to achieve a 122Msps max sample rate/bandwidth setting.

Could a branch be created on this repo be created that uses Nuand's gr-osmosdr and somehow have the Soapy wrapper capable of activating the features? I would be happy to test.
