Use jai-imageio-core 1.3.0 instead of jai_imageio 1.1

[stain]

Avoids GPL-incompatible JPEG 2000 dependency by using the forked jai-imageio-core instead of jai_imageio 1.1.

See jai-imageio/jai-imageio-core#15 and
jai-imageio/jai-imageio-core#4
for relevant discussion with dcm4che2
user @RemiSgt

Note that jai-imageio-core renamed com.sun.media.imageio
to com.github.jaiimageio - hence changed import statements.

The tests pass, but I was unable to build it correctly (before changing this) as Maven fails with:
