Patch #27397: Improved DPX/Cineon code

Patch by Julien Enche, thanks!

From the patch comment:

It allows Blender to load:
- 1, 8, 10, 12 and 16 bits files. For 10 and 12 bits files, packed or
  filled type A/B are supported.
- RGB, Log, Luma and YCbCr colorspaces.
- Big and little endian storage.
- Multi-elements (planar) storage.

It allows Blender to save :
- 8, 10, 12 and 16 bits file. For 10 and 12 bits files, the most used
  type A padding is used.
- RGB and Log colorspaces (Cineon can only be saved in Log colorspace).
  For Log colorspace, the common default values are used for gamma,
  reference black and reference white (respectively 1.7, 95 and 685 for
  10 bits files).
- Saved DPX/Cineon files now match the viewer.

Some files won't load (mostly because I haven't seen any of them):
- Compressed files
- 32 and 64 bits files
- Image orientation information are not taken in account. Here too,
  I haven't seen any file that was not top-bottom/left-right oriented.
