Removed key Terrain_Radiation in [EBalance]. It is redundant with --enable-eb and cause segfault is --enable-eb is provided and the variable is set to false.

Removed old view factor writing code. Moved view factor writing to Ebalance constructor and added a pure virtual view factor getter in TerrainRadiationAlgorithm

Moved all the solar panel part to complex, added interface to implement it in other modules. Still some cleaning needed in complex (move some parts to SolarPanel.cc), and a correct implementation for config keys and for output path is still required

Removed useless omp loop in the constructor, in order to be able to use push back on radfields vector and avoid dummy object contruction

Now solarAzimuth and solarElevation are passed as argument to terrain_radiation::getRadiation, so there is no need in Complex to store a pointer to radfields, so it is celaner. Note these two values are used only in complex

Added new output grids in radiation. ILWR_terrain now just writes ILWR, terrain LW not yet taken into account
