[Open Assets] Speedometer: How fast am I? v4

Speed display should be much more accurate now, I/O should be considerably less jank, should no longer randomly turn off

Update I've been sitting on for at least a few months. Features:

• Fewer bad code practices. This was one of my first mods and my first hud mod, I was still learning how hud draws work then and made some less than stellar setups for previous versions of this mod. As a result though, this version should work more consistently with all non-green resolutions
• MRCE: if mrce is loaded and its custom hud is enabled, the speedometer will be shifted up so it doesn't overlap
• The speedometer will now read vertical movement as well instead of only horizontal when measuring speed, allowing for a more accurate reading

Should now actually function properly in netgames, each player having their own speedometer, instead of reading globally for all players
Also now supports I / O to save your display setting

Forgot to remove debug script. It was commented out, but still. Also forgot to set default option to FU / T

the speedometer now properly scales with hud transparency settings, and fades along with the rest of the hud
