fix(modeling): added fromNoisyPoints() to plane

[z3dev]

Thanks to @Hermann-SW , the current implement of plane.fromPoints() was found to be very limited, requiring a set of vertices that is both planar and ordered.

See #1321 for the issue.

These changes add a new function to calculate the best-fit plane across any set of vertices. Testing has shown some differences in precision, and fromNoisyPoints() always produces a normal in the positive orientation.

Given that fromPoints() is used internally and produces a directional normal, the new function was created.

@platypii What do you think? I was kind of surprised at the current implementation of fromPoints(). It's correct but requires careful positioning of vertices. But in the general sense, a best-fit version is probably better for users.
