v3.0.0

🚨 Breaking

• Renamed function/tag partial as pattern.

🚀 Features

• Added support for subroutine definition groups via (?(DEFINE)…) at the end of a regex.
• Added TypeScript declarations, and improved JSDoc-based types. (#6, @rauschma)
• Testing improvements to make tests pass with Node.js 14+.

🐞 Fixes

• Fixed an issue with interpolating a regex with numbered backreferences into a pattern with lookbehind, which could throw in edge cases.
• Fixed an issue that could allow subroutines to reference lookbehind in edge cases.
• Fixed edge case issues with subroutines that referenced groups containing backreferences to themselves.
