[VOTE] 42.2.16 release candidate 2

Hi,

pgjdbc 42.2.16 release candidate 2 is ready for review.

The release fixes multi-dimensional processing.

Arrays sent in binary format are now sent as 1 based. This was a regression for multi-dimensional arrays as well as text/varchar, oid and bytea arrays.
Since 42.2.0 single dimensional arrays were stored 0 based. They are now sent 1 based which is the SQL standard, and the default
for Postgres when sent as strings such as '{1,2,3}'.
