Write content on how RO-Crate can be consumed and why it is useful

[elichad]

From internal meeting notes a few months ago:

Need to make it clearer the way RO-Crate can be consumed – add generic archetypes to the Website, not just use cases. Acquiring metadata gradually in a heterogeneous ecosystem, exchanging metadata with other ecosystem. “Five things you can use RO-Crate for”. RO-Crate Patterns of Usage. Make it a bit interactive. Highlight how it is useful. Transparency is different from provenance.
