improve support for -S2

Browse Source 
got myself an adafruit "qt py -S2" with tinyUF2 bootloader. So I wanted to get that working. And it does work :-).
FFT time = 10ms (instead of 2ms on classic ESP32)  is a very good result, also virtual USB runs much better now.

// there are two things in these MCUs that could lead to problems with audio processing:
// * no floating point hardware (FPU) support - FFT uses float calculations. If done in software, a strong slow-down can be expected (between 8x and 20x)
// * single core, so FFT task might slow down other things like LED updates
