d0435ef2 - pep508: add `PartialOrd` and `Ord` implementations to `MarkerTree`

pep508: add `PartialOrd` and `Ord` implementations to `MarkerTree` Since we're adding a `Option<MarkerTree>` to `PubGrubPackage`, and since we just make `PubGrubPackage` implement `Ord`, it follows that we want `MarkerTree` to also implement `Ord`.
