dfd839de87 add braces around potentially-empty (debug) else branches 
the compiler advises "suggest braces around empty body in an 'else' statement [-Wempty-body]". We follow.

dce3b04695 update for filter coefficient 
Seems that I made a small mistake when calculating cut-off frequencies. Updated values make more sense.

d3af3446f7 add bandpass filter for PDM mics 
This introduces an optional band pass filtering step to remove low frequency noise. Very effective for PDM mics - reduces noise floor by a factor of 100 !

4bd35b780e Some improvements for I2S Line-In 
- I2S DAC devices utilize the complete sample range [-32767 ... 32768], while I2S microphones typically deliver  samples in [-2047... 2047]. Down-scaling Line-in samples ensures that filters and AGC operate optimally.
- use aPLL clock source for I2S with MCLK
- experimental: I2S slave mode (however could not get it to work ...)

8847d47bee cherry-picking from audioreactive development 
A few goodies from my development branch, before I continue refactoring so much that I can't extracts nothing anymore.
- GEQ fades a bit slower
- updates to mic profiles
- simple peak detection without FFT (low freqs only)

64441b39ac critical bugfix 
it's possible that volume samples become negative. In this scenario, our simple noise gate does stupid things, and it looks like "effects temporarily lost the sound".
This fix improves the situation, and makes sure that volume samples are always >= 0.

1ae0dd574d fix for ADC analog 
the "wait until I2S buffer fills" trick does not work for ADC sources, as the I2S sampling does not run in background for ADC.

fb00bef05f AR - necessary constants for 166Khz sampling rate 
16kHz might be a good compromise on small MCU's:
- GEQ will show frequencies up to ~6Khz
- FFT process may use up to 32millis (-> 100% CPU load). Try to stay below <60% so FreeRTOS can schedule all tasks properly.

- more CPU time is left for other WLED, so it maintains LED FPS and stays responsive on web UI.

d7bc6b1be7 AR: optimization for small MCUs, part2 
Only run FFT when the result will be used.
Please note that this also means that `FFTTime` shown in Info is only meaningful when there is sound input and not silence.

--> To get exact FFT times, the optimization can be disabled by compiling with `-D SR_DEBUG`

a766ddbebc make I2S microphones work with buggy IDF4.4.x 
I2S microphones were not working any more in with the newest framework - only delivers silence.
Ther reason is stupid bug in espressif I2S "compatibility" driver: RIGHT and LEFT channel are swapped, so when only asking for LEFT, we get silence from RIGHT.

Workaround: simply change LEFT to RIGHT, until the problem is fixed in ESP-IDF --> Fix tested on "classic ESP32", but still need to check behavior on -S3.
Code compiles also on -S3, -S2, and -C3.

smaller changes:
- a few changes to use new APIs (MCLK, rouing and sample resolution)
- a few additional debug messages
- put correct value into _pinConfig.mck_io_num
