explicit simd store -- opposite of Simd::from_slice

[programmerjake]

currently we have to either cast the dest pointer to Simd<T, N> and use write_unaligned or use an array-typed store, this is somewhat likely to cause issues at some point. plus, having a function on Simd is nicer than having to figure out to use *dest = *val.as_array().

There is also slice.copy_from_slice(vector.as_slice()).

There is also slice.copy_from_slice(vector.as_slice()).

yes, but that also isn't a vector store, it's basically an array store again.
