HOPKINS: Add sanity check to parsing of COMPUTAN.TXT file.

This previously crashed on the Polish version due to a variant file
format causing the parsing to make several invalid memory accesses.

This prevents this crash and any other in future, though it does not
fix the parsing of the variant file format.
