Decimal types are not checked against max precision/scale at table creation

[ion-elgreco]

Environment

We are not checking the max allowed precision/scale during table creation, which could potentially allow users to create tables that do not respect the protocol limitations on decimal types.

Example:
"schemaString": "{\"type\":\"struct\",\"fields\":[{\"name\":\"x\",\"type\":\"decimal(65,64)\",\"nullable\":true,\"metadata\":{}}]}",
