0.23.0 - Unreleased

Requires NamedGraphs v0.14. The network types here are AbstractNamedGraph subtypes, so its breaking changes carry through to them, including the output types of vertices and edges and the return values of the mutating functions. See the NamedGraphs changelog (#384).
The leaf type of a contraction sequence is ITensorNetworks.Key, where it was NamedGraphs.Keys.Key (#384).
