increase E131 max universes from 12 to 112 (esp32 boards only)

Browse Source 
* use a more meaningful max universes limit of 112 (safe up to 128x128 pixels)
* accept more universes, but only track sequences for the configures max universes
* made e131LastSequenceNumber[] local (its only used in e131.cpp)
