Some optimizations in FASTPATH mode, to ensure that audio processing takes places as soon as new samples are arriving:
* raise fftTask prio to 4 (above async_tcp) - to ensure that other gimmicks (MQTT, IR, alexa, live preview (ws), json API, or web UI) cannot cause delays by preempting audio.
* changed the "be nice" condition in AR::loop
audioSyncPacket contains four "invisible" padding bytes added by the compiler. These need to be initialized to zero, as future versions of the protocol will make use of these fields.
* remove double Wire.begin() - Wire cannot be re-initialized; its already started by pinManager.joinWire()
* Only use global I2C pins; make sure that audireactive I2C settings are aligned with global I2C pins
* minor cleanup
* remove I2C pins from AudioSource::initialize()
Note to self: sdaPin, sclPin are just dummy values now, good for UI consistency, but unused otherwise. Could be removed.
* debug messages added to different initializers
* SPH0654::initialize() was having a wrong signature: uint8 instead of int8.
C++ can be a real bastard ;-)
* npm run build
* enable CI build for esp32_4MB_S and esp32S3_8MB_S (both optimized for speed)
* add animartrix to esp32S3_8MB_S
* workaround for gcc ICE (only happens with V4 framework and -O2 optimize for speed)
* it seems that `WiFiUDP.flsuh()` does something completely different from 8266, and its actually causing WLED to stall on UI calls. So not usable on 8266.
* fixing a few compiler warnings about "comparing signed and unsigned"
NB: its a hotfix, we have to check if there are other problems on 8266. Also its definitely ugly, but it helps as a band aid.

In contrast to upstream, MM follows a "no pin stealing" approach, so the Wire interfaces are only initialized when needed.
pinManager.joinWire() will take care of the details, and will return false if something went wrong.
* DC blocker: use higher quality filtering on boards with FPU (-S3 and classic esp32)
* experimental: build option to increase audio task priority - reduces latency
