Note: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-11312
We currently have TimestampArray::from_vec and TimestampArray::from_opt_vec in order to provide timezone information. We do not have an option that uses FromIter.
When implementing this, we should search the codebase (esp Parquet) and replace the vector-based methods above with iterators where it makes sense.
