Updated netcdf-4 reader for EUMETSAT raw data

[Ian Culverwell]

EUMETSAT have altered their netCDF-4 data format. (Basically, another level of data, 'science_data', has been included in the netCDF-4 group structures.) This change requires a change to the ropp_io_read_eumdata subroutine of ropp_io_read_netcdf_get. Axel von Engeln has sent me some updated code that handles this (attached), and three test datasets (also attached).

This code has been merged with the ROPP71_prototype branch. It tests out fine on the example datasets, on which the earlier version fails now, of course. The smaller (~0.6MB) of the three example datasets, GRAS_1B_M02_20120909000057Z_20120909000118Z_N_T_20131031144444Z_G15_NN.nc, has been copied to ropp_io/data/eum_test.n4, and its results on ifort have been copied to the relevant reference files for the t_eum2ropp and t_eum2bufr tests.

Passes the ROPP7.1 test folder so closing ticket. (Note that a query about non-empty stderr files has been swept up into this - see ​http://www.romsaf.org/view_admin_enquiry.php?id=177 for details.)
