SIMD-accelerated gas mixtures. (SIMD atmos) (#2479)

Browse Source 
* SIMD atmos

* Moles will always be a multiple of four.

* Component dependencies for grid atmos.

* Let's optimize allocations while we're at it!

* Inline this

* A bunch of atmos optimizations

* Fix crimes against atmos

* Microsoft moment

* Remove nuget.config

* do not reference Robust.UnitTests in Content.Benchmarks as it's unneeded.

* Revert "Remove nuget.config"

This reverts commit 872604ae6a51365af4075bb23687bd005befd8ac.

* Gas overlay optimization and fixes

* Lattice is now spess

* minor atmos tweaks
