Revise the script to directly read fontforge font files, which are generated in the makefile. This permits overriding the fontforge path during the build, and executing fontforge in parallel with make -j. Avoid duplicating download URLs in the script, which ensures that the script itself works without network access, e.g., when downloading the data files on a developer machine with network access and executing the script on a build machine without network access.
