Adding TFH Module

[Sparlight]

Hey there!

I caught sight of this neat input translator, so I went ahead and made edits to add support for Them's Fightin' Herds. Please let me know if you see any issues with this or feel free to make any edits you see you need!

It's been a long time since I've made active contributions to anything on github, and I'm normally a C# developer these days, so there's a chance I missed something important. Running locally, however, I'm finding this works fine.

Thank you!
