Bugfix in raw data reader classes. The bug affected the determination of the raw data size in case the Common Data Header is missing (RequireHeader option is set false). All the reader classes now check if the data size found in the CDH is compatible with the size found in the equipment header. In case if it is not compatible, one uses now the size from the equipment header. This basically represent the situation when the CDH is there, but it is not filled correctly.
