Support for Highway Gothic font

[ZeLonewolf]

The Highway Gothic font is used in United States highway signs and route shields. Support for this font would allow for US-centric maps to display highway shields and other highway-related features using the same type face used in the real world.

There are 8 variants of Highway Gothic, including: "A" (the narrowest), "B", "C", "D", "E", "E(M)" (a modified version of "E" with wider strokes), and "F".

These fonts are in the public domain (as US government works) and have been recreated in a few places, including: https://github.com/sammdot/roadgeek-fonts.
