New Feature Incubation Repo: webxr-hands-input

Hello, immersive web folks.

Based on conversation in proposals Issue #48 <https://github.com/immersive-web/proposals/issues/48>, I've created a new feature incubation repo for work on hand input for WebXR:

Manish has volunteered to be the feature champion. Thanks, Manish!
