add `LightClientHeader` wrapper (#4481)
The light client data structures were changed to accommodate additional
fields in future forks (e.g., to also hold execution data).

There is a minor change to the JSON serialization, where the `header`
properties are now nested inside a `LightClientHeader`.
The SSZ serialization remains compatible.

and https://github.com/ethereum/beacon-APIs/pull/287
