Updated the NetCDF files produced from the Met Office's data zoo.

These changes have come about through changes to Iris, rather than changes to the data themselves. Most notably, the sample_data/A1B_north_america.nc and sample_data/E1_north_america.nc have changed their dimensions to be time, lat, lon rather than forecast_period, lat, lon.
