Bus wrapper modifications

Browse Source 
- NeoPixelBus update 2.8.3
- automatic selection of appropriate I2S bus (`X1xxxxxxMethod`)
- removed I2S0 on ESP32 (used by AudioReactive)
- renumbered internal bus numbers (iType)
- added buffer size reporting

Bus modifications
- WWA strip support
- bus initialisation rewrite
- optional parallel I2S (ESP32, S2 & S3)
