v0.4.0

Added

• Adds CHANGELOG.md which will be better upkept moving forward.
• Adds MaybePointer to assist with deserialization which should not fail fast.

Changed

• Pointer::new now accepts a generic list, so &["example"] can be replaced by ["example"]. For untyped, empty slices (i.e. Pointer::new(&[])), use Pointer::default().
• std is now enabled by default.

Removed

• Removes optional MalformedPointerError from Pointer.
