**
** The sha3_query(Y) function evaluates all queries in the SQL statements of Y
** and returns a hash of their results.

** The SIZE argument is optional.  If omitted, the SHA3-256 hash algorithm
** is used.  If SIZE is included it must be one of the integers 224, 256,
** 384, or 512, to determine SHA3 hash variant that is computed.
