The serialization implementation is heavily
inspired by the existing trait implentation for
`std::num::Wrapping<T>`.
The deserializing implementation maps input values
that lie outside of the numerical range of the
output type to the `MIN` or `MAX` value of the
output type, depending on the sign of the input
value. This behaviour follows to the `Saturating`
semantics of the output type.
