NetCDFIO: Introducing the STRICTFORMAT config parameter for the io.ini when using the NetCDFIO plugin to read or write meteo data. This paramater is by default set to false meaning that meteo parameters that are not present in the CNRM standard for NetCDF files will also be read and written. Setting STRICTFROMAT to true means that only parameters defined in the CNRM standard will be regarded when reading and writing meteo data, all other meteo parameters will be ignored.
