A2 Questions

Does A2 support Callibration?
input_level_dbu, output_level_dbu accessors on NeuralAmpModelerCore DSP
slimmable_weights accessors on NeuralAmpModelerCore DSP
standard values for slimmable_weights? 

Implement NAM Model Weight selection UI

NAM INput VU is f*ed up.

File Player Underrun is NOT CPU use related. There's an underrun somewhere.

Update Pi 4 Benchmark Results:

The benchmark is to run TooB Neural Amp Modeler with an A1 model to generate 100s of audio. Lower times are better.

TooB NAM has a compile-time switch that uses either the NeuralAudio NAM implementation or
the Neural Modeler Core NAM implementation.
