[C++] Implement timestamp to date/time cast that extracts value

[asfimport]

Change casting from timestamp to date/time to extract the value, instead of just truncating as we currently do (which rounds, giving incorrect answers, in some cases). This should also be a safe cast by default (unless you want to do something like cast from timestamp[ns] to time32[s] which may overflow).

This should behave like Postgres DATE/CAST(... as TIME), or Pandas Timestamp.date/Timestamp.time.
