RGB matrix effect - left-right gradient (#7742)
* Left-right gradient. * Update the comment to match the new functionality. * CPP does integer division so this round is not necessary. * The x-range is actually 224, update comment and use bit-shifting again. * Update docs with gradient left-right effect and associated "DISABLE" option.
