Disable Jasper & re-enable OpenJPEG.

Jasper failed to read a large jp2 file & OpenJPEG will get large file
support.  @rouault is making more OpenJPEG improvements, [including
support for files with > 4 billion
pixels](uclouvain/openjpeg#730 (comment)).

Build against OpenJPEG master. Eventually it may work with the jp2
files I have.
