Tests/JPEG2000: Add a simple JPEG2000 test

Browse source 
We can't decode any actual image data yet, but it shows that we can
read the basics of the container format. (...as long as there's an
Annex I container around the data, not just an Annex A codestream.
All files I've found so far have the container.)

I drew the thes input in Acorn.app and used "Save as..." to save it as
JPEG2000.  It's an RGBA image.
