Separated reading of soilph and soilbulk into new files. By default these variables will now be read from the file soil_bulk_and_ph.nc stored at the shared accounts.
In sechiba.card, now copy soils_param.nc and soil_bulk_and_ph.nc instead of soils_param_fao_cn.nc. The values for soiltext are the same in soils_param.nc and soils_param_fao_cn.nc. The values for soilph and soilbulk are the same in soils_param_fao_cn.nc and soil_bulk_and_ph.nc. The files are all stored on the shared accounts.
No change in results.
