CreditNotes: Add GET filter by CreditNoteNumbers Similar to Invoices functionality
Invoices has a filter of InvoiceNumbers. But this functionality is missing from Credit Notes even though Credit Notes are basically a negitive invoice. We need to be able to query for the status and existence of Credit Notes but keep hitting our API rate limit. We are using an WHERE OR statement but it's slow and we cannot check more than a few credit notes at a time.
