DecodeProof decodes the proof of a data item from a byte array encodedProofString is the base64 string of the proof see EncodeProof for more information returns the proof as a struct.

EncodeProof encodes the proof of a data item into a byte array encoded in big endian Structure: - 1 bytes: version (uint8) - 2 bytes: poolId (uint16) - 8 bytes: bundleId (uint64) - chainId (string, null terminated) - dataItemKey (string, null terminated) - dataItemValueKey (string, null terminated) - Array of merkle nodes: - 1 byte: left (true/false) - 32 bytes: hash (sha256) returns the proof as Base64.
