Expand Operand variants

[rukai]

it looks like Operand the equivalent of sqlparser::ast::value::Value doesnt yet parse the cassandra native types https://cassandra.apache.org/doc/latest/cassandra/cql/types.html

It wont be able to differentiate between types like int and tinyint but those can be combined into a single int type

The native types are not in the operands as they represent the information available in the Update, Insert, and Select commands. No data type is, only string representations. The only place DataType is present in the query is in the alter table, alter type, create aggregate, alter column, create function, create table and create type statements.

For queries the data type is not available until there is a result from the server and then the types are embedded in the metadata for the rows.
