Upload personalized attachments with sendtransactionmail endpoint

As a developer I want to trigger transactional emails with personalized attachments using a single REST API call.


Right now personalized attachments can only be uploaded via HTTP API in a seperate call. It's inconvenient to implement 2 APIs and also produce doubled the overhead.
