Is your feature request related to a problem? Please describe.
I see that Reference Tables are a preview feature, so maybe they are not fully integrated into the REST API and OpenAPI spec yet, but I was wondering if it's possible to create and/or update the data in a Reference Table via API. I would love to keep some reference data synchronized with data we master in Snowflake and was going to make a simple tool to do so using this client.

Describe the solution you'd like
Support for creating and updating the data inside a Reference Table.

Describe alternatives you've considered
Manual edits through the UI.

Additional context
Thanks.
