Needs a column for JPL vs Hamilton #3

See document for details https://github.com/godotengine/godot-docs/issues/6271

The math for conversion from JPL or Hamilton is take x,y,z,w where x,y,z is the axis and multiply the axis by -1. W is the scalar like 1.

Thanks! I didn't know that. It looks like these are two versions of quaternion multiplications as described in: https://arxiv.org/abs/1801.07478 , right? I'm open to adding a column to the table.
