Version 0.4.0

- The manual_range_contains Clippy lint will no longer fire.
- Some constructors and getters have been made `const`.
- RANGE and new_wrapping have been removed, as their implementations had
problems with overflow.
- Access to the `bounded_integer` crate is now always required in the
macro, even with the `serde` feature disabled.

Version 0.3.0

- Bounded integers are now #[repr(transparent)] around the type they are
stored as.
- #[repr(..)] is no longer necessary on the declaration, the smallest
type is automatically chosen.
- The inner value of a bounded struct is now inaccessible to prevent
breaking of invariants in the same module.
- Z0 has been renamed to simply Z.
- The std::iter::Sum and std::iter::Product traits have been implemented
where possible.
- More comparison and arithmetic traits are implemented.
- From<bounded type> has been implemented for primitives where possible.
