Deserializes Stream Length and an extra 4-byte field (which might be the address of the
 map when it was previously stored in memory) from the bytes parameter starting at the
 index offset and uses it to provide necessary information for the Stream to be usable.
 Generally, deserialization is part of the step of loading the Stream information from
 persistent storage (disk)
@param reader {@link PdbByteReader} from which to parse the information
@throws PdbException upon not enough data left to parse
