Re-Introduce Font Compatibility

[Inertia-Squared]

• Re-added @azealo 's font compatibility code after being overwritten by later commit
• Changed fallback typeface to Franklin Gothic Medium Condensed - fits the UI better (vs. Arial) and is somewhat similar to the font used in the video
• Added check to allow use of old font if it exists in typical location (also made it work regardless of user!)
• Removed a redundant math import, might as well while I was there ¯\_(ツ)_/¯

seems like for usability, custom font should be a getopts / option, and it should default to ./visuals/whatever.ttf; just using a font from the local folder makes it so this runs on macos / linux.

Just trying to keep the default behaviour but add a fallback for those that don't have the font like myself, the intent was to make it non-invasive to the original functionality while improving compatibility.

@carykh a lot of people are opening issues due to this error, would it be ok to merge?

Looks good to me
