Programmatically infer event's local time zone ID

[saumier]

Develop capacity to programmatically infer a local time zone ID (TZID) to all Artsdata-minted Place entities.
Time zone information should be represented in a manner that complies with the IANA time zone database.

Three options can be considered for retrieving time zone information:

• Downloading a local copy of the IANA time zone database;
• Calling a time zone API;
• Retrieval via Wikidata Place item via “located in the administrative territorial entity” > “located in time zone” (data quality could be inconsistent)
