Feature Request: Download example H5Ps with setup

[bracken]

It would be great to be able to fetch some examples for the types when setting them up. It is easy to create your own example or go find one and download/upload it to this dev environment, but it would be nice to be able to start working on a type with a fully-robust example for a type (or multiple examples if available).

Something like:

• h5p core --download-examples
• h5p setup h5p-course-presentation --download-examples
• h5p examples h5p-course-presentation

I'm not sure what would make most sense. It could just fetch the public/open licensed example from https://h5p.org/content-types-and-applications
