feat(GODT-2283): Reject message imports for messages > 30MB 

feat: Implement NetError (and rename proton.Error to proton.APIError) NetError is an error type returned when no response was received from the API. This allows callers to determine whether their call failed due to a network level error. Additionally, proton.APIError now has Status to see what the status code was in the response that triggered the error.

fix: Don't send 2FA information during Authentication 

fix: Only access response object if there is any 

fix: Only use first key to encrypt attachments and drafts 

feat: Perform draft encryption during upload 

fix: Set unread flag from draft template 

fix: simulate token rejection as API 

test: Add test comments 

fix(GODT-2114): check disposition before uploading an attachment.
