add version check for lal*-data packages
Currently there is no version check for the lal*-data
packages, however data files could change then we would need to ensure that a compatible version of the data files are installed. Need to think of the best way to version these and check for a compatible version. This is mainly an issue on Debian where was can have multiple versions of the shared library packages installed and these different shared library packages may hae different compatibilities with the data files.
