Adding direct support for JPEG 2000
Historical Note
- GDCM uses already JPEG2000 in order to manage compression in DICOM images.
- The Openjpeg library is carried by ITK in the Utilities directory. (an old version...)
- However, ITK currently doesn't

Community Requirements
- Streaming (reading region of interest, without having to load the entire image)
- Need to update to OJ v2, since v1 does not support this (see tiles support)
- Subsampling (reading subsampled versions of the image)
- lossy/lossless
- Pixel types
- 8-bits (signed/unsigned)
- 16-bits (signed/unsigned)
- 32-bits (signed/unsigned)
- Multi-Channel
- Jpeg 3D
- Time series ?
