Review comment:
The proto lib is compiled for the lite runtime so it has no `toString` of
its own. Added just the bits used in the table factories.

> BigQuery to Beam SQL timestamp has the wrong default: truncation makes the

> Most of the time, a user reading a timestamp from BigQuery with
> higher-than-millisecond precision timestamps may not even realize that the
> data source created these high precision timestamps. They are probably
> timestamps on log entries generated by a system with higher precision.
> If they are using it with Beam SQL, which only supports millisecond
> precision, it makes sense to "just work" by default.
