Add tool for extracting bitmap fonts from .fnl files (font archives). This is mainly for testing the underlying .fnl reading code, which is needed for proper font rendering in the MangaGamer version of Sengoku Rance. In the future this tool could be updated to support rebuilding font archives, which would allow adding special glyphs, using condensed fonts, etc. Credit to CookieWukk for reverse engineering the .fnl file format.
