OLCI mountain shadow around nadir view creates artefact #52

OLCI mountain shadow around nadir view creates artefact. The reason is that view angle tie point grids have discontinuities around nadir. Simple Interpolation between those values is wrong, but can be fixed with a more advanced interpolation which was already used in SaRONG project.
