to have more stable frame times, the minimum delay should be calculated from the time BEFORE strip.show() not after.
This optimization increases CPU load and potentially has negative impact on usermods that check for strip.isUpdating(), so its only enabled with WLEDMM_FASTPATH.
* robustness: Segment::height() should never return 0
* Segment::XY(), Segment::virtualWidth() and Segment::virtualHeight() declared inline in fx.h. The compiler will always inline these functions now, avoiding overhead of call/return. "Knowing" the function body might also enable other optimizations.
--> up to 10% speedup in 2D effects.
using a dynamic array for newSamples[num_samples] was never needed. It was a risks as the buffer was allcated/deallocated with every call of getSamples().

FX.h: add ledsrgbSize and allocLeds()
FX_fcn.cpp:
- copy constructor: allocLeds()
- move constructor: no change
- copy assignment: reuse! + allocLeds()
- move asignment: no change
- resetIfRequired: no free
- setUpLeds/resetSegments: allocLeds()
unless...: copy constructor aften called. That is the bad boy causing re-allocs at every effect change!
* PSRAM_Allocator was missing the "reallocate" method, which lead to undefined behaviour when dynamic JSON doc needed to grow/shrink
* Segment::setUpLeds() quickfix for length() == 0 (should not happen, but it did happen for me once)
* leds in PSRAM causes major slowdown on wrover boards - disabled.
* prevent string buffer overflows (stack corruption)
* avoid division by zero (program might crash)
* avoid log(0) which is undefined, too
* use faster math routines for float (logf, powf)
* customMappingTable: allocate using calloc instead of new (new will throw exception if nor enough heap)
* fixing a few minor memory leaks
* ws.cpp: catch out-of-memory in sendLiveLedsWs
* ws.cpp: change interval to 80ms (120 ws very slow...)
