The SwissFEL .geom files name their pixel mask with an absolute facility path, so the sets read a
copy beside the original (jf-16M_mask.geom, mbco_march_mask.geom) whose mask_file is relative to the
copy's directory; only that line differs. EXTERNAL_TEST_DATA_STILLS.md says how to make them.
On a 2000-frame subset of the int16 MbCO set, before (geometry without masks + --mask-good) and after
(the geometry's mask and bad regions): indexed 98.2% both, R_FREE (--model) 0.244 -> 0.234.
