* Fix: uart-uhci compiling errors * Enhance Esp32Camera functionality by adding optional byte swapping for RGB565 format. Introduce SetSwapBytes method to enable/disable byte order swapping, and update Capture method to utilize an encode buffer for improved memory management and performance during image processing.
