[#18164] jpeg2000 patch, with some fixes from Peter too.

Support for jpeg2000 and writing DCI Cinema standard files.

Notes
* 12 and 16bit channel depths are converted from/to blenders float buffer.
* Grayscale/RGB with alpha supported.
* Theres an option to save color channels as YCC rather then RGB.
* Quality 100 saves lossless
* The UI is a bit weired because of the DCI standards need to be given to the encoder.
