(Not for now) Plugin Distribution

[JordanAlec]

Plugin distribution

Currently plugins live in the dtk repo.
Future options could include:

• Remote plugin registry (fetch plugin manifest from a URL)
• Local plugin path support (dtk add ./my-local-plugin)

Side Note

This isn't decided yet however I do like the local plugin approach so that users can share plugins without direct contributions if wanted.
The remote plugin registry is likely overkill until a large number of plugins have been built

tracking: I've not had a need for this but could potentially be useful. Its been simple to extend privately where I've wanted to so not actioned this. I will keep open for now but this may get deleted or unactioned until needed
