[JOSS] How is GHI/DNI converted to radiances? #122

Description

@AdamRJensen

Could you elaborate on how GHI/DNI is converted to radiances? Also consider revising the sentence as it is not very clear at the moment.

In `simshady`, two major types of input data need to be provided. First, a 3D scene is built that represents the environment, consisting of primary objects for simulation (e.g., PV panels or target buildings) and surrounding objects that may cast shadows (e.g., neighboring buildings, trees). These objects can be provided as Wavefront .obj files or as Three.js geometries. Second, weather and climate data need to be provided as input data in .json format by aggregating irradiance data such as Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) datasets onto sky domes, for example by assigning irradiance values to each sky segment [@Górski_2005; @zonca2019healpy].

    This took a bit more time, since I was not responsible for creating the solar radiation input data at that time. I consulted @MartGro and we reformulated this section Software Design - Input data quite a bit.
