Add compatibility for custom font sizes on bounding boxes

[mrdbourke]

As of PIL 10.1.0+ the size parameter is available in PIL.ImageFont.load_default(size).

This enables the font_size parameter in draw_bounding_boxes to be used even if font=None.

See PIL docs: https://pillow.readthedocs.io/en/stable/reference/ImageFont.html#PIL.ImageFont.load_default
