Calculate spectral_irradiance_field with Disort including a sun source.

Prepares actual input variables for Disort, runs it, and sorts the output into cloudbox_field.

This version uses the C implementation of Disort based on ::run_disort.

Altitudes, temperatures, VMRs and PNDs shall be provided with lat and lon dimensions removed
