Changes to Adafruit_CircuitPython_OV5640 doubled the memory usage for a given quality setting. This makes the latest release of in CircuitPython incompatible with the previous quality setting=3 + colorspace=adafruit_ov5640.OV5640_COLOR_JPEG due to that working out an an allocation size of 204800. This is too much for the first Pico. Here is the breaking change: adafruit/Adafruit_CircuitPython_OV5640#35 Quality 4 is still too large at 153,600 bytes. Quality 5 using 122,880 works.

Note that Pico 2's could handle quality 3. May follow up with a subsequent PR that automatically picks the best quality for arbitrary platforms.
