big optimization possible here; this uses sse2 despite my build command being RUSTFLAGS="-Zlocation-detail=none -Zthreads=4 -C target-cpu=native" cargo +nightly b --profile profiling

(where my cpu supports SSE4_1 and SSE4_2)

the packed_simd crate requires a nightly compiler, so unless we're willing to work with a nightly toolchain, it won't build.

oh yeah, and this should probably be moved over to terraforge, because thats where orbit calculations are done, iirc.
