Imrpoved sound quality in analog_audio_app, and added Nyquist protection option to BBW filter for praline. (#3054)

* Added PRO button to analog_audio.cpp for debugging metallic ringing sounds in Audio app. Ensured consitency to 4MHz in analog_audio.cpp

* Restored blutooth after loss.

* Added several sampling rates to analog_audio for testing.

* Ran format-code.sh

* Fixed 0x03 mode for DC/Q-INV/Q-SHFT being set at every tuning and sample rate change. This was the root cause for loss of bluetooth before. Sample rate, and frequency can now be changed without need for manually resetting DC/Q-INV/Q-SHIFT settings. Updated method for setting frequncies in praline so that we have more testing options.

* Ran format-code.sh and cleaned up stale comments.

* Addressed comments, and removed commented line, opting for higher register values, 5E and 5D. Added WFM Debug View to support testing demodulation ringing.

* Addressed comments in PR conversation to clean comments and ensure consistency at initializtion accross updated methods and displays.

* Ran format-code.sh

* Set initial legacy state. Improved readability of clocking initialization settings. Updated set_sampling_frequency, and udpate_bandwidth to set decimation values in the fpga_registers to avoid aliasing in low band frequencies.

* Updated clock_manager to use correct clock and clock parameters for audio pll. Ran format-code.sh.
