Package Hook Implementations Separately #670

The underlying hook implementations currently used by IDOM may have applications beyond just this library. For example, the react-ipywidgets by @maartenbreddels could leverage the same hook definitions for its own uses. Additionally, with the advent of technologies like Pyodide it's possible that these hook implementations might even outlive this project.

Work should be started on this after:

• Use context is implemented: Add Use Context Hook #585
• Use debug value is implemented: implement the use_debug_value hook #566
• We rename this package: Should we rename this repository/package? #645
