Disabled checks and reasons:

These are all basically unavoidable in HPC numeric code:
-readability-magic-numbers
-cppcoreguidelines-avoid-magic-numbers
-cppcoreguidelines-pro-bounds-pointer-arithmetic
-readability-function-cognitive-complexity
-bugprone-easily-swappable-parameters

This doesn't work very well:
-clang-analyzer-optin.mpi*

This is a suggestion, and is perfectly fine:
-misc-no-recursion

Expensive (and noisy, because we let exceptions escape from `main`):
-bugprone-exception-escape

TODO: This would be good to fix and re-enable:
-misc-non-private-member-variables-in-classes
