hhpReadConfigStreamReads the full imager configuration as a single stream of data into a buffer. The buffer contains all the configuration items in an
ASCII stream so that it can be written to a disk for storage. No interpretation is done on the data stream, therefore, the data
stream contains both read only, and read/write data.
