Picked apart by JLsoft on Sat Oct.7th, 2k out of need from using the PM4.2 demo

This might be a common/standard format, but I couldn't find anything using .SPR
that was similar in the 5 minutes I bothered searching. If it is, let me know
above so I actually get the format RIGHT :)

 =[Description]================================================================

- 8 bit color
- All frames are same size
- Each frame has it's own palette
- Palette bytes are: RGBRGBRGB...
                     \_/\_/\_/
                      0  1  2
  * Palette bytes need to be divided by 4 for the 0-63 VGA palette range

 =[File format]================================================================
                         This might be wrong...a 16-bit frame speed? Ouch :P
