`shiny create` requires `requests` python package

[dskard]

Release 0.6.1 introduced a dependency on the requests package. When I try to use shiny create without having previously installed the requests package, the command fails:

$ python -m venv venv
$ . ./venv/bin/activate
$ pip install shiny

Can the requests package be listed as a dependency so it gets installed automatically when shiny gets installed?

Thanks for finding this.

I think it would make sense to switch to the urllib library, since that one is part of the standard library, and we only use requests.get() in one place.

This has been fixed in v0.6.1.1, which has been merged into main.
