Implement std::hash::Hash for Ksuid structs.

[aurelien-clu]

closes #6

Motivation

It would be useful to implement std::hash::Hash so Ksuid and KsuidMs could be stored inside HashSet and used as keys for HashMap without wrapping them or converting them into a string.

Solution

impl Hash for Ksuid {
    fn hash<H: Hasher>(&self, state: &mut H) {
        self.0.hash(state);
    }
}

// same for KsuidMs

Tests:

• Ksuid and KsuidMs can be stored inside an HashSet
• hashes are deterministic

If the PR is validated, would you like me to add another commit to bump the version and update the changelog? Or you prefer to do it yourself?
