 At the moment the only way to work around the lack of a proper
 `#[repr(pack = "N")]` attribute is to use `#[repr(packed)]` and then manually
 fill in padding which is a burdensome task. Even then that isn't quite right
 because the overall alignment of the struct would end up as 1 even though it
 needs to be N (or the default if that is smaller than N), so this fills in a gap
