ESP32 Port Incomplete Features

[embedded-creations]

• C-shaped Chaining of panels to create multiple rows is broken (Z-shaped is working)
• Simplify/split main ESP32 MatrixHardware.h file so that there is is one hardware type included per header
• Refactor ESP32 MatrixHardware.h files so that RGB signals can be swapped easily by user without breaking address lines
• malloc matrixUpdateFrames buffers before other smaller buffers as they are (by far) the largest buffers to allocate?
• LoadMatixBuffers() Allow lower color depth to increase display size / refresh rate for ESP32
• AnimatedGIFs sketch could have performance improved: there's a lot of time spent waiting for a swapBuffers() call to complete, as it needs to wait for the next frame transition, which is just wasting time if the frame rate is set relatively low to allow more sketch CPU time for GIF decoding).
• Only updating panel buffers when there are Layer changes, reducing CPU usage even further
• APA102 strip support (bringing to parity with the new Teensy APA102 driver that's in this branch)
• Refresh fails at higher display sizes: 128x32 is largest that has been seen working. Not sure about cause of failure
• Scrolling text speed is maximum one pixel shift per frame, which is quite slow with slow calculation framerates - need to allow scrolling text more than once per frame?
