It's beautiful how these traits just magically work

I took the liberty of switching to use ArrayData equality and renaming the AsArray method to byte_view. Whilst bytes is perhaps more consistent with the as_bytes() method, I think it is better to be consistent with the naming of the type (as_bytes is probably named incorrectly)
