Enable fission heating tallies in the random ray solver

[nuclearkevin]

Description

This PR adds tally support for fission heating (kappa-fission) in the random ray solver. This includes additions to the automagic multi-group cross section setup to generate heating cross sections. A new test has been added to hit the changes (random_ray_auto_convert_kappa_fission).

It seems as if the test failures are caused by gcovr failing to generate C++ coverage. I don't think this has anything to do with the changes here (#3702 seems to be running into the same issue). If anyone could provide advice on getting gcovr to cooperate it would be greatly appreciated!

@nuclearkevin I have two PRs (#3715 and #3716), one or both of which should resolve the gcovr issue. Please wait on one of those to be merged; at that point, retriggering the CI here should pass since it always uses a merge commit with develop (i.e., you don't need to update your branch).
