Bandwidth setting for 2023.02 unclear with increased sample rate

[jcmartin]

Presently, the valid bandwidth range returned for bladeRF 2.0 on release 2023.02 from (bladerf_get_bandwidth_range): [200000,200001..56000000]. bladerf_get_sample_rate_range returns [520834,520835..122880000].

The newest release now supports a sample rate of 122.88MHz, and the demo on the nuand website shows a spectrogram of 80MHz. It is unclear what the user should set the bandwidth to in order to maximize the returned bandwidth.

• If the user should set the bandwidth to 56000000, I suggest that this be documented.
• If the user should set the bandwidth to 112000000, I suggest that bladerf_get_bandwidth_range reflect this value.
