/**
* Registers a schema `union` — a value that may be any one of several variant

* @param name Schema type name, e.g. 'session.ProxyConfiguration'.
* @param selector The schema's `selector` node for this union.
* @param options
* @returns The registered union — `build(data)` resolves and constructs the matching
* variant outbound, `fromWire(payload)` resolves and parses it inbound.
