trino-python-client returns dtype string for datetime/timestamp fields

See original GitHub issue

presto-client returns data type of string for a timestamp field. Setup:

PrestoSQL 333
PostgreSQL 12.1
presto-client 0.300.0

Tested:

Using the PrestoSQL JDBC driver, the field is returned as a Java timestamp.
Using psycopg2 driver with SQLalchemy directly to Postgres, the field is returned as a python datetime object or pandas timestamp object.
Using presto-client 0.300, the field is returned as a string.

Expectation:
The field should be returned as a python datetime object or pandas timestamp object, akin to the PostgreSQL driver.

Note:
The issue has also been reported for pyhive (no longer under current development). I have not tested PrestoDB’s version to see if the other team has also worked on the topic.
