If the .dat files are meant for PostScript interpreters only, then
they can be compressed using PostScript filters. I have written
some scripts:

Using LZW the needed space would be 41 MB,
using Flate method the needed space is 32 MB.
The latter one has the disadvantage, that the PostScript interpreter
has to support Language Level 3.

The needed space can be further decreased by about 4-5 %, if
unnecessary white space is removed from the .dat files previously.

Herbert, what do you think?
