Problem: different result from `eth_getProof` comparing with Ethereum

[macong-cdc]

Describe the bug
Result from eth_getProof RPC method is different from Ethereum EIP-1186

To Reproduce
Steps to reproduce the behavior:
You may try

curl --location --request POST 'https://evm-t3.cronos.org' \
--header 'Content-Type: application/json' \
--data-raw '{
    "jsonrpc": "2.0",
    "method": "eth_getProof",
    "params": [
        "0x4CecAA8ad42Ba5c0D69C6F68a273901C6fd52B02",
        ["0x1"],
        "0x588200"
    ],
    "id": 0
}'

Expected behavior
accountProof and proof under storageProof in the json returned are not hex-strings.

it seems geth simply encoding bytes as hex string with 0x prefix
