Provide GRX compatible files

[SuperIlu]

Please consider to also provide the typeface in GRX/Allegro compatible FNT format. BDF can be converted to FNT using https://github.com/SuperIlu/GrxFntConv

This is a niche use case which I think does not warrant inflating release tarballs for everyone else. Users wanting GRX files can convert them themselves and use them in their projects.
