Point interpolation of surface fields.

The default way to specify the position is by rtp_pos.

Linear interpolation is applied.

The interpolation is done for the latitude and longitude in rtp_pos, while the altitude in rtp_pos is not part of the calculations. However, it is checked that the altitude of rtp_pos is inside the range covered by z_surface with a 1 m margin, to give a warning when the specified position is not consistent with the surface altitudes.
