New mode option available when uploading records
When a user is uploading records to a dataset through /datasets/:id/records:load to an existing dataset with records, they can use?mode=appendwhich adds new records or updates existing records with the the current upload.
Append mode cannot be used on empty datasets. If the schema of new records being uploaded do not match the dataset an error will be returned.
