[Feature] Add Circle Equation Calculator

[R2-STAR]

Description

A Circle Equation Solver is helps solve or derive key characteristics of a circle based on its equation. Specifically, it can take an equation of a circle (in either standard or general form) and calculate the center and radius of the circle, or it can convert between different forms of the equation.

A Circle Equation Solver takes an equation of a circle and either:

1)Extracts the center and radius from the equation.
2)Converts the equation from one form to another (e.g., from general form to standard form).
3)Solves for unknowns, such as the center coordinates or radius, based on the given information
