Resolve "crackling" sounds in analog_audio_app ( #3068 )
...
* Updated PRALINE audio processing methods to account for potential slip in 25MHz reference clock. Moved all clocks to PLLB except for CLK0 to isolate the ADC from potential EMI and clock spills from the other clocks to CLK0. Added PLL reference to Clock ui_debug display and added debug view for PLLA and PLLB. Updated PRO menu in analog_audio_app to allow for 100Hz resolution in sample rate for finer control of samplerate debugging of crackling noise artifacts. Updated ppb method and set it for account for a potential 49 Hz shift in the PRALINE crystal. Started instatiating methods for synchronized DMA transfers for the spectrogram since the FFT calculations and the LCD data updates appear to be related to the crackling noise.
* Added firmware/flash.h to .gitignore.
* Changed reference clock for start_audio_pll to 40MHz instead of ~12MHz xtal. Moved clocks around to reflect best audio quality in analog_audio_app at 3.072 MHz sample frequency.
* Ran format-code.sh.
* Removed ppb in set_sampling_frequency since it created aliasing in analog_audio_app.
* Expanded baseband_bandwidth back to 1750000 after testing since audio quality was retained.
* Updated comments to address copilot recommendations where acceptable.
* Removed firmware/flashsize.h from .gitignore as coordinated with @gullradriel.

Significant performance hit when declaring on stack. C++ wants to initialize std::array or even raw array with element constructors, was resulting in ~7% CPU utilization, for a buffer that was immediately written over anyway.
