I agree on principle when writing endian-neutral code requires some
extra infrastructure or considerably more code, but here we are talking
about trading a call to `to_ne_bytes` for one to `to_le_bytes`, which is
zero effort.

... although the Sashiko warning on `extend_with_padding` *would*
require more than just a method call to properly manage arrays of `u32`
and `u64`, so maybe we don't need to fix them all, or any at all for
that matter since half-fixed code is still broken code.
