Fixing `inversion inversion(circle, circle)` #341

Closed yarusome closed 1 year ago

yarusome commented 2 years ago

This PR fixes the function inversion inversion(circle, circle) with a formula derived and verified using complex numbers. (#143)

Note: This function, like many other functions in the section of inversion, treats points as if they were in defaultcoordsys. This will be addressed in a new issue with a separate PR.
