As a researcher, I want to put my accession numbers in and get an RO-Crate out #7
Description
A top level function which takes in the accession numbers for samples/sequencing/assembly/etc, retrieves the metadata from databases like ENA, builds the crate connecting the pieces together, and returns it to the user.
The user should not need an in depth understanding of RO-Crate.
Depends on #3
