4d03af6466 mic quality dropdown, cleanup 
* mic quality: When set to "low noise" or "perfect", only minimal smoothing is performed on the "Mic Volume" input.
Every filter adds a delay, so this option can lead to better on-spot responses from effects.

* cleanup: removed a few unused variables and unused code.

7d04660b91 postProcessFFTResults adjustments for FastPath

7883474404 postProcessFFTResults minor refactoring 
* limiter on/off : made the logic a bit clearer.
* use a simpler way of writing filters: a = n*a + (1-n)*b --> a = a+ n*(b-a)

no functional impact.

e98858c751 audio FASTPATH, part 2 
* introducing sliding window FFT, which effectively doubles the rate of samples - and FFT results - produced per second. As a side-effect, it also makes FFT a bit less noisy.

As sliding window FFT requires double the number of FFT runs, the feature is only enabled on esp32 and esp32-S3.

9803cecee2 new idea to reduce stack buffer usage 
the JS string can be shortened, by putting the usermod into a variable `ux` that is used instead of repeating the string 'Aduioreactive'.

For now its just an experiment, to see if the idea works on several browsers.

899899094f sound sync: use last remaining gap to transmit soundPressure 
* use last remaining two bytes in audioSyncPacket for transmitting soundPressure
* 0x0 is treated as "legacy value" --> soundPressure = volumeSmth;
* decodeAudioData: ensure receivedPacket struct members  are correctly aligned -
strictly speaking it is not safe to cast a uint8_t* as it does not offer any alignment guarantees.
* remove 8266 special handling in audioreactive::setup()

5a377103b5 small accuracy improvement 
(int)currentResult is a truncation, so we need to add 0.5 for proper rounding.
also changed inefficient "constrain" into faster max(min( ...))

6e24850073 ar_energy: improved energy reconstruction 
fftResult[] is indended to look good on GEQ, and has a very "twisted" representation of FFT results only. This change improves reconstruction of signal energy, by on-doing some of the "GEQ enhancements" in fftResults[].

70bfbd5a43 ar_energy: fix a math error 
fixing mis-optimized math when calculating energy.
energy = sum(amplitude^2). this is not the same as sum(amplitude)^2.

Example:
1+5+7 = 13; 13 * 13 = 169
1*1 + 5*5 + 7*7 = 75
