Can you expand the supported file types for the rewst forms? Right now, it's only UTF-8 and I have a few use cases to upload PDF's which are not supported. Zapier handles this using something called Hydration/Hydrate where you can upload just about anything (seemingly) and pass it along to any other webhook. It seemingly treats the file as a long string. Some details are here https://community.zapier.com/show-tell-5/how-to-hydrate-a-file-with-a-get-request-15656
