Adding a jules_prescribed_dataset

Hi Maria

I’ve had a look at the log files from your latest run of the suite and notice that instead of segmentation faults you’re now getting errors that say ‘register_input_file: Each input file must provide data for the entire run’. This is probably because data_start and data_end are the wrong way round under [namelist:jules_prescribed_dataset(7)] in the current version of rose-app-fire.conf. (It’s easy to miss; it took me a long time to spot it.)
