OpenTK.Core 4.0.0

Huge thanks and congratulations to the entire OpenTK Community for getting this release together. Key changes: Full support for .Net Core 3.1 Brand new GLFW-based windowing system Brand new GLFW-based input system Removed all platform-specific backends (and fixed every xplat bug!) Math library performance improvements and fixes All new OpenAL bindings All new OpenCL Bindings Total restructure of all packages into a modular system with a number of packages. The OpenTK package is now a metapackage that will automatically download all of these for you. OpenTK 4.0.0 is entirely MIT licensed.
