v3.0.0

This is a huge release! We've packed in all the requested breaking changes to put us on a solid path of API stability going forward. We have removed all of our required dependencies (no more Thrust or GLM!) and dramatically simplified our directory structure and CMake. We have upgraded internally to double precision and added MeshGL64 for those who need to access it. And we have simplified and improved the API in many ways and added a few powerful new features. Please check out our new and improved C++ and TypeScript docs pages!
