CDXL DataType, a replacement for CBM cdxl.datatype.
animation.datatype subclass.

Features are:
- Supports palette-per-frame. Now CDXL streams like "Voyager.CDXL"
  are correctly played back with the correct colors.
  (requires animation.datatype V41)

- Supports animation.datatype V41 ADTA_TicksPerFrame
  The higher timing resolution avoids the nasty sound clicking
  (because audio playback speed and video playback speed
  differs slightly due rounting errors - ADTA_TicksPerFrame
  avoids this because it is much more exact than ADTA_FramesPerSecond).

Planned features:
- A CDXL encoder

- Support for the chunkypixel CDXL codec (gfx-card fans would be very happy,
  I think...).
  But I need more info about this format...

- Support for the YUV codec
