ETS-C1P0-p0_12.j2k-compare2ref & NR-C1P0-p0_12.j2k-compare2base failing under windows

Those tests are failing under AppVeyor since AppVeyor update on November 6th.

I think I know what is going on here: on windows, depending on the way git is configured, git will convert LF to CRLF if it thinks the file is a text file. So, the test is failing because the corresponding PGX reference image gets corrupted by git checkout. See here for more details.
