Hello, 

This request is to add a new table named `checkout_session_custom_field` that works in a similar way to the `invoice_custom_field` table. 

Within the Stripe API, checkout sessions can contain an array of custom fields. This request is to make that information available via the tables ingested by the Fivetran ingestion processes. 

This feature would be very helpful for organizations that use Stripe Payment Links, as custom options on those forms are tracked within custom fields on a checkout session.
