Improve comment and style for quality range checking
Comments on lines: 1490, 1497 use range verbiage such as:
"""Controls the JPEG quality. Valid range is from 2..55 inclusive"""
However, 55 is not included.
Also, the check on 1495 uses the following checking style using '<':
if not 2 <= value < 55:

Would 55 work? I wonder if the < 55 is a bug, as opposed to <= 55

I do not know if the hardware would be happy with 55. But the driver is certainly unhappy:

   cam.quality = 55
   print(f"Attempting to use quality {quality}.")
   b = bytearray(cam.capture_buffer_size)
   jpeg = cam.capture(b)

produces:

Traceback (most recent call last):
File "code.py", line 81, in <module>
File "adafruit_ov5640/__init__.py", line 1499, in quality
ValueError: Invalid quality value 55, use a value from 2..55 inclusive  

If we want to match the style used for saturation and 55 is invalid for quality, we should change the comment to say "54 inclusive" and use '<='.
