Replace three f-string logger.debug calls in tests/utils.py with %s
placeholders so the log message acts as a format string and removes
G004 from the ruff ignore list now that no violations remain.

Contributes to #3327.

Rename two variables.

Decoding a 1-bit /Indexed FlateDecode image used a pure-Python
img.getpixel loop over every pixel. Replace it with vectorised
Pillow point/merge operations, reducing extraction time for a
2550x3300 scan from ~2.2s to ~0.035s.

Closes #3850.
