Getting ready for Arduino IDE Library Manager#29

Select frame buffer location by pixel format: keep raw RGB/GRAY in DRAM, keep JPEG in PSRAM. Check sensor set_pixformat/set_framesize return values during init. Re-apply pixel format after framesize setup to preserve requested RGB565/GRAY. Validate captured framebuffer format against requested image format. Remove RGB565->BGR565 post-copy swap and silence unused capture mode params. Signed-off-by: Ozan Durgut <ozandurgut.2001@hotmail.com>

Use pixel count as the iteration bound instead of inImg->size. inImg->size is byte-based for RGB888, but the loop indexes pixels with i*3. Using size as the bound can overrun input/output buffers and produce invalid grayscale conversion results. This aligns iteration with pixel indexing and prevents out-of-bounds access.

Add RGB565 byte swapping in serial_send() for ESP32 UART output. When image format is RGB565, payload bytes are now swapped in chunks using a static transmit buffer before Serial.write(). This keeps the wire format compatible with host-side decoders expecting RGB565 byte order. Non-RGB565 formats keep the existing block-based transmission path.
