Pull Request Overview

This PR adds a new erf_zeros function to compute the zeros of the error function erf(z) in the first quadrant of the complex plane. The implementation leverages the existing cerzo function from the specfun library.

• Adds erf_zeros function that returns an array of complex zeros
• Updates module exports and documentation to include the new function
• Adds comprehensive test coverage comparing against scipy reference values
