Grzegorz MartensandClaude Opus 5.5 cb1e573c08 M11: tests for packing in other one-component spaces, mixed Group 3 and Flate after resampling ...

Mutation testing found three behaviours no test held:
- eight-bit black-and-white in calibrated grey, an ICC profile of one
  component or a separation is packed, each keeping its colour space,
  and calibrated RGB of only 0 and 1 isn't (taking every array colour
  space for an indexed one passed every test);
- mixed Group 3 (/K 1, with end-of-line codes) is stored again as
  Group 4 (taking /K above 0 for Group 4 passed);
- a resampled Group 4 image of vertical stripes is stored as 1-bit Flate,
  which is smaller (ruling Flate out for any CCITT image passed).

From reviews with the pdfcraft-review skill.
