* Add intermediate structures for bytes conversion * Expose byte conversion methods from `Eth1Service` * Add eth1 ssz containers * Fix type errors * Load eth1 cache on restart * Fix compile errors * Update Cargo.lock * Add comments and minor formatting * Add test for eth1 cache persistence * Restrict Deposit and Block cache field visibility * Add checks * Fix `SszDepositCache` check * Implement Encode/Decode directly on `BlockCache`
