safe_solve

Safely inverts a matrix using regularization if needed

A general-purpose implementation of synthetic control methods
that accounts for potential spillover effects between units. Based on
the methodology of Cao and Dowd (2019) <doi:10.48550/arXiv.1902.07343>
"Estimation and Inference for Synthetic Control Methods with Spillover Effects".
