To build this palette, I did the following:

* Created the .asn + .obj files by hand
* Referenced them in a .set file and asked WH40K_TD.exe to render the sprites
* Screenshotted the output and used GIMP to create a 1x255 image with them all
* Exported that image as an ASCII .ppm file
* Used the `generate_palette` script to output Go code \o/

Note that palette index 0 is ignored, and hardcoded to be transparent black.
This is because 0x00 seems to be used as a record separator in .obj files, so
can't be used as a palette index anyway.
