if moduleName contains a slash, use a different module/path

[maartenbreddels]

This is useful if a package contains multiple widget extensions (I use this for ipysheet).
For instance, use:
_model_module = Unicode('ipysheet/renderer').tag(sync=True)
The embed manager will try got get ipysheet/renderer.js from the server its running on (which is a valid request, and useful for local testing), if that fails it will fetch:
https://unpkg.com/ipysheet@semver/dist/renderer.js

Does this need to special case @my-namespace/mymodule ?

[maartenbreddels]

Indeed, good call. Do you see any other issues with this?

The only other issue I see with this is that it still inserts the dist/ - is there a way we don't have to hardcode that portion either? I don't see a way to have it nicely support both the other widget managers, but perhaps you have an idea?

In the notebook this works without issues, requirejs handles it without issues, Jupyter lab also doesn't mind the extra slash in the registry. I think the 'dist/' part is ok, I see it as a manager specific implementation.

Oh right - it is very specific to how the html manager is fetching things.

Looks good to me, then. Thanks!
