Celestial Impact DXV

This is a simple RLE-based format used in Celestial Impact intro file.

First 32-bit value in the file is the number of frames, then frames follow (each prefixed with 32-bit size). Frame data is 141172 bytes of data compressed with RLE; this data includes 400x300 image, 768 bytes of palette, and seemingly unused data. RLE compression is simple: top bit of the opcode tells whether it is a run or copy, bottom 7 bits tell run/copy length.
