Installation hints

4.9.1

• build with intel/19.0.3, due to an compiler error full optimisation does not work
• prerequisites: hdf5, netcdf, antlr, gsl, udunits2
• passed through most checks, except expected failures. omp-related checks did not work - possibly due to missing omp environment. Since nco is mostly IO-limited, this should not matter. omp-capabilities are not tested yet.
• install script
