Kim De Mey 36d430aaa2 Add headers with proof content type and use it for verification (#1281) ... * Add headers with proof content type and use it for verification - Add BlockHeaderWithProof content type & content - Use BlockHeaderWithProof content to verify if chain data is part of the canonical chain - Adjust parser & seeder code to be able to seed these headers with proof - Adjust eth_data_exporter to be able to export custom header ranges for which to build proofs (mostly for testing) There is currently quite some ugliness & clean-up needed for which a big part is due tos upporting both BlockHeader and BlockHeaderWithProof on the network. * Change accumulator proof to array / SSZ vector type - Change accumulator proof to SSZ vector instead of SSZ list. - Add and use general buildProof and buildHeaderWithProof func. * Make the BlockHeaderWithProof an SSZ Union with None option * Update portal-spec-tests to master commit		2022-11-04 09:27:01 +01:00
