* Test the validity of the packet, for reading

* A packet will be in an invalid state if it has no more
* data to read.
*
* This behaviour is the same as standard C++ streams.
*
* Usage example:
* @code
* float x;
* packet >> x;
* if (packet)
* {
* // ok, x was extracted successfully
* }
*
* // -- or --
*
* float x;
* if (packet >> x)

* @endcode
*
* Don't focus on the return type, it's equivalent to bool but
* it disallows unwanted implicit conversions to integer or
* pointer types.
*
* @return True if last data extraction from packet was successful
