5.3 Convert field files between XML and HDF5 format

When Nektar++ is compiled with HDF5 support, solvers can select the format used for output of .fld files. FieldConvert can be used to convert between these formats using an option on the .fld output module. For example, if in.fld is stored in the default XML format, it can be converted to HDF5 format by issuing the command

FieldConvert in.fld out.fld:fld:format=Hdf5
