Retrieve multiple terms by ID

[marius-mather]

Is your feature request related to a problem? Please describe.

As far as I can tell, there is no way to retrieve multiple terms with a single API call, even if you know the ID for all the terms (e.g. the IRI). Is it possible for any of the term lookup endpoints (e.g. /api/terms) to accept multiple values for IRI, and return all the matching terms

Describe the solution you'd like

The /api/terms input could accept multiple iri parameters and return the corresponding terms:

Additional context

As an end-user of the OLS4 API, I often find myself doing multiple individual lookups of terms to retrieve their details - retrieving multiple terms in one call could benefit and end-users, and presumably also lead to lower resource use by OLS4 instances.
