UPGRADE

Upgrading from 1.x to 2.0

Added support for deserializing raw attachment contents. In order to achieve this an optional $attachments argument has been added to the deserializeStatement() and deserializeStatements() methods of the StatementSerializer class as well as to the StatementResultSerializer::deserializeStatementResult().

When being passed, this argument must be an array mapping SHA-2 hashes to an array which in turn maps the type and content keys to the attachment's content type and raw content data respectively.
