Added support of J2K codec for Jpeg2000 writing

This codec is absolutely needed to generate DCP using OpenDCP,
before that external application to convert JP2 to J2K was used
which slowed down export a lot.

New codec is exposed to image format settings panel and called
Codec. Default one is JP2 which creates files with .jp2 extension,
new one is called J2K which creates with .j2c extension.

Other changes:
- Fixed avi jpeg warning which was treating as error here.
- Made it so extension is detecting from ImageFormatData instead
  of image file type, which makes it possible to have different
  extension for the same file type depending on it's settings.

  IRIS format should still be changed (depending on number of
  channels it'll be .bw, .rgb or .rgba extension)

- Default image format settings would be set from image buffer
  when re-saving it. Makes it possible to easily open .j2c file
  and save it using J2K codec (without this change it'll save as
  .jp2 using JP2 codec)
