small, but quite big update - tyres mod (Patreon)

I updated the mod's post, you can download it again. There's a bunch of changes in it, some of it is testing. The biggest update I have, is the new tread pattern options in the parts selector. Currently "High Poly Wheels New 3 Div" is the best, but there's no adjustable sub divisions on the tread yet.

other things we've done;

- align sidewall nodes, for better deform

- remove friction loss for super high res

- add sliding friction comp?

- limit "weight -> tread stiffness" calculation

- make it so people can have no paired nodes

- remove dupecheck

- added "treadReinfOptions" in case vehicle mod creators want to have the slot available

- scintilla looses stability at ?? speed? (apparently floating tyres at speed. Paired nodes?) (probably)

Now tyres should be better at speed with the "High Poly Wheels New 3 Div" version. I won't remove the old ones, but keep in mind that they are going to be depreciated for the new pattern.
