Real reference dataset for the [large] JFJochProcess_LysoRotation test, stored with git-LFS
(tests/data/*.h5). lyso_rotation_master.h5 is the 1800-image lysozyme rotation series
(its data files keep the names the master links to). The test indexes it at 100% with cell
~78.2/78.2/37.8; it SKIPs when the data is not pulled.
