FormatCBFFull does not work with compressed files

[dagewa]

The file LCLS_jungfrau-jungfrau_multipanel.cbf in the image_examples directory on dials-data is a large file, the 4th largest in that directory with a size of 17 MB.

It is uncompressed, but if I try to compress it, then it fails to read, with an error raised in FormatCBFFull

$ dxtbx.print_header LCLS_jungfrau-jungfrau_multipanel.cbf.bz2 
=== LCLS_jungfrau-jungfrau_multipanel.cbf.bz2 ===
