Fixed issue where both P0 and P1 moments were displayed in the diffusion coefficient results. With this fix, the Legendre filter is successfully sliced. Also, there was previously concern that get_condensed_xs needed to be specially catered toward DiffusionCoefficient. However, since the MGXS get_condensed_xs method condenses the tallies before calculating the cross section, that should work great for DiffusionCoefficient as well. Tests updated.

Fixed several bugs related to decay-rate
...
1) In mdgxs.py, DecayRate, get_xs(). There is no need to reverse the order
since there isn't an energy group filter anymore. Also, the new_shape
addition formats the cross section like all the others. I updated
mgxs_library_hdf5 test results accordingly.
2) In material.cpp. If you use a macroscopic dnesity other than 1.0,
the code still pushed back '1.0'. My change fixes that. Using a macro
density other than 1.0 wasn't tested anywhere, so I modifed mg_convert
to take a density of 1.1. The default macro density of 1.0 is used in
many other tests.
3) tally_scoring.cpp. Notice that the score is accumulated, then sent
to the function score_fission_delayed_dg where the tally is accumulated.
This amounts to "double accumulation". It makes sense to accumulate the score
over the delayed groups if there is no delayed group filter, but in this
case, when delayed group filter is not None, the score needs to reset
each time.
In other parts of SCORE_DECAY_RATE, I think the distinction between
accumulating and resetting the score is correct. The only place I wasn't
sure was line 1057 (and its equivalent in multi-group, line 1962).
It's too bad the decay-rate isn't tested very thoroughly. Although I
don't have time to do it myself, I think adding a DelayedGroups filter
to the mg_tallies test would be a good start.

Added ability to handle ArbitraryMatrixXS types (i.e., we can now create (n,3n) energy transition matrices). This is in addition to the previous commit's incorporation of the same for vector MGXS with the ArbitraryXS type. Also gave the user the ability to request that a domain's macroscopic Chi values be used for all isotopes in a domain. This is important because some codes do not create macroscopic Chi's with flux-weighting of the group-wise fission source, they instead assume a constant group-wise flux. This leads to errors downstream with microscopic MGXS in codes like OpenMC's MG mode and even heavily used production codes like DIF3D.
