Description

CALCITE-5349 added several improvements for creating org.apache.calcite.rel.externalize.RelJson such as the withOperatorTable, withLibraryOperatorTable and, withJsonBuilder methods.

However, the only method to deserialize JSON with the RelJson class is a the static readExpression() which creates a generic RelJson.

It would be advantageous to have a RelJson instance method capable of deserializing JSON into a RexNode after it has been customized.
