Parametric Toroidal Prop

So we all heard this MIT toroidal propeller thing, I decided to make a parametric one so you can experiment with your own parameter.

Update 12 Feb 2023
Just made an updated version, please find the file marked as v2, you can compare it with the original version
Updated features :
- Center holder cylinder has a separate diameter config
- Parametric numbers of toroidal prop
- Overlapping toroidal props are fixed
- Adaptive cw ccw based on extrude twist value

Update 13 Feb 2023
Someone requested a babyhawk version of this propeller, so you'll find some new files here
Updated features :
- Code refactoring, module based to simplify & reduce repetition. Rename some variables
- Parametric side hole for screwing your prop, default parameter compatible with the emax babyhawk, you can modify to t-motor style as well
