Sample rate limitations

[mehdideveloper]

Is there the possibility to put some limitations on the sample rate value?
For example AirSpy accepts only two values: 2.5MSPS and 10MSPS.
It's not an important thing; Just a small recommendation

Thanks for the hint @mehdideveloper

Limiting sample rates (and available gains etc.) will be possible with #148 .

Added this to task list in #148. Will close this one.
