Highlights:
- DeepCShuffle2 node replaces DeepCShuffle; full parity and same interface as the classic Shuffle node (Foundry did not expose the new knobs created for the Shuffle2 node, so it's not possible to match that without a lot more work; plus I kinda prefer the old Shuffle node).
- vendor in DeepThinner to fulfill the longstanding promise to add some kind of Deep compression
- update the build system for easy building of Linux and Windows builds.
- all noise types now support 4d noise
- fix some longstanding bugs
Note: Windows build is untested, but completed without errors; I don't have a Windows system available to test.
