In Altair, light client sync protocol exchanges `BeaconBlockHeader` structures for tracking current progress. Wrapping `BeaconBlockHeader` inside a `LightClientHeader` allows future extensions of this header, e.g., to also track `ExecutionPayloadHeader`. Note: This changes the JSON REST format by adding a `beacon` nesting. For SSZ, the serialization format stays same (but overall root changes).
