v0.8.1 tests refactor (#326) * Introduce new mocking proc to replace: - makeFakeValidatorPrivKey - hackPrivKey - getNextBeaconProposerIndex - addBlock - makeBlock * Add comments on datastructure unsynced with the spec * Add merkle tree constructor and initial mocking for deposits (missing merkle proofs) * [Mock] Implement sparse merkle tree and merkle proof builder * [Mocking] Genesis deposits * Add compact_committees_roots init + mock genesis state * [Tests] Add first deposit test using the new mocking procedures * [Tests -deposits] add at and over 32 ETH deposit tests * [Tests - deposits] Add test for validator top-up * [Tests -deposits] Mention the TODO to test for invalid conditions * [Tests] Add stub to test "is_valid_genesis_state" * [Merkle proofs] Implement round-trip checks * Deactivate roundtrips test * SSZ - use EF convention for hash_tree_root / hashTreeRoot * [Tests - Attestation] Attestation mocking + initial test * Add mocking + 3 new tests for valid attestations + mention future invalid attestation tests * Add crosslinks test (1 failing to attestations in block being duplicated in state transition) * Single attestation crosslink test - workaround https://github.com/status-im/nim-beacon-chain/issues/361 * Add test for failed crosslink penalty * Rebase fixes + add refactored tests to test suite * justif-finalization helpers first batch * Add 234 finalization tests * Fix justif test, Rule I 234 finalization does not happen with sufficient support. (Also unittest check template does not fail properly in some cases) * Add tests for all finalization rules * Properly delete nim-byteutils following https://github.com/status-im/nim-beacon-chain/commit/c91727e7e5f9c7a95a634055e94e9d3bcb6cc41a#diff-7c3613dba5171cb6027c67835dd3b9d4 * use digest helper for deposit root
