I created a python script that utilizes numpy and the multiprocessing libraries to speed up the computation. I don't really understand the file format very well, but I made a start at it, right now you can load rle files but the rules aren't interpreted, so anything aside from the standard will produce uneventful results. At least until I fix it.
I thought you guys would get the most use out of this, enjoy:
