- Switch from lookup tables to adjustable close approximations
This also gives a buff to the symmetrical airfoil as before it had an incorrect peak lift coefficient

- Rework fin types to just "Flat" and "Standard" airfoils
Flat plate remains the same, while Standard becomes a customizable airfoil that can perform both as a symmetrical and cambered airfoil depending on the camber setting. Increasing the camber slightly increases the angle at which the airfoil stalls in positive AoA but strongly decreases it in negative AoA. Need to make some of these values less hard coded but this works for now.

- Invert low pass setting so it's on by default
Also slightly strengthened the low pass filter to try to help with low mass high area things spazzing easily

Use resource.AddWorkshop instead

Remove pointless extra checkbox for debug options

Add ability to calculate center of lift if contraption framework is installed

Add E:fin3GetPropellerRPM()

- Low pass filter on propellers to prevent spaz
- Add SF library
- Add function to get AoA of fin

Fix null physobj error and incorrect initial lastPos on primitives

Changed think hook to tick hook

Propeller tool!

Remove unnecessary function causing issues with primitive fins
