MikeHeiber/Excimontec: Density of States Bugfix

This bugfix release corrects the density of states (DOS) and density of occupied states (DOOS) sampling during the steady state transport test to correctly calculate the DOS and DOOS distribution data with the correct magnitude so that the integral of the DOS is the total density of states and the integral of the DOOS is the total charge carrier density.

For a detailed listing of all changes, see the Changelog.
