Update to the OAI-PMH API

An updated version of AMCR OAI-PMH API is released featuring two main changes – now the endpoint automatically translates to the most recent version, preventing the API to return mixed versions of the records, and subsets of set heslo are now available to allow requests for specific vocabularies.

Changes

• The generic OAI-PMH endpoint (https://api.aiscr.cz/oai) now automatically translates to the most recent version, preventing the API to return mixed versions of the records. Previous version can by still reached directly by calling approprite endopint version (e.g.: https://api.aiscr.cz/2.0/oai, https://api.aiscr.cz/2.1/oai, https://api.aiscr.cz/2.2/oai)
• New subsets of the set heslo are available to allow requests for specific vocabularies. See https://arup-cas.github.io/aiscr-api-home/oai-pmh/#sets for details.
