Security fix and refinements

Fix for potential Denial of Service vulnerability

Summary: The fix prevents the RawDataParser.php‎ to enter an endless loop under certain circumstances which would lead to memory exhaustion.

Details: When parsing a specifically crafted, malformed PDF file, the low-level RawDataParser enters a state that leads to uncontrolled memory allocation. This continues until the PHP script exhausts its memory_limit and crashes with a fatal error. An attacker can leverage this vulnerability by submitting a small, malicious PDF file to any service using this library, causing the server process to crash and become unavailable.

Thank you Yang LUO (https://github.com/N0zoM1z0) for reporting this and the provided details on the matter. #​787 contains further information.
