GitHub: #50
To make installation easier for users of Homebrew on Apple Silicon, add /opt/homebrew to the default paths searched when trying to find the underlying re2 library. While doing so, add an extra fallback to /usr (instead of only searching /usr/local).
Note we still search /usr/local first to avoid accidentally changing behaviour for existing users (e.g. suddenly compiling against a different version of re2 in /usr).
