Ledmap persistent/consistent and showing in segment graph +small changes

pio.ini: remove ping pong clock from _all
ce.js: change on error handling
liveviewws2D: add colorAdjust
json.cpp: ledmaps will be stored in json/info 
settings_2D: fieldChange at loadJS

FX_(2D)fcn.cpp:
- loadedLedmap default 0 (default)
- loadedLedmap active then only use if index <size

index.js:
- global ledmap set to active value
- draw to drawSegments
- gradient colored leds
- add ledmaps to graphics
- add fetchAndExecute (from custom effects), used by drawSegments to get ledmap contents
- graphics bigger in non pc mode
