new NCBI Nucleotide web translator

Using the Entrez Eutils JSON API. This is a translator for datasets, and therefore has some limitations, e.g. apparently no author information.
That's unfortunately not what you're looking for. See https://www.zotero.org/support/dev/translators/coding#related

The `seeAlso` field is for establishing item links between items being imported at the same time-- this should probably be a link attachment.
