 Add the possibility to use a fixed vertical molar fraction profile for the 
 collision-induced absorption like the correlated-k.

+== 26/02/2024 == GM
+
+Add thermal conduction from thermosphere. The conductivity for each gas is 
+calculated with the interpolated akk*T**skk formula and the total conductivity 
+of a mix of gases is calculated according to Mason & Saxena (1958) semi-empirical
+formulation.
