support for ro-crate metadata

[pvgenuchten]

RO-Crate is a metadata convention within academia to describe datasets in a sidecar approach. Would be nice to have import and export options from MCF

(Some) Academic repositories pick up the embedded RO-Crate metadata via a signposting convention

Some deposits including RO-Crate metadata:

• https://doi.org/10.4121/21304308.v1 (Notice the RO-Crate button in sidebar)
• https://doi.org/10.5281/zenodo.5753092
