Started adding Jacob points.
Untested, but building Jacobian add...
Added jacobian mult, but still broken as hell.
Shit is still broken.

Doubling seems to work, point addition fails for the Y segment for both
mixed and non-mixed currently.
Basics working. Convert to different formulas.

Tried to imp my equations.
Got it working… or so I thought.

The equation itself is wrong! Need to revist and figure out how to fix
it, or how to do inverse without multiplication.
