This is an update to #372 which is now obsolete, and adds robust SSZ support to get_header() and submit_block():

  • Support for multiple ACCEPT types
  • Support for dynamically converting SSZ requests when the relay only supports JSON
  • Ability to translate transparently from the type returned by the relay back to the type requested by the client (e.g. SSZ (client request) -> JSON (relay request / response) -> SSZ (client response))
