[Feature Request] Decode WriteSetChangeWriteTableItem.data to not null

[0xbe1]

🚀 Feature Request Description

Currently, the data?: DecodedTableData; field in WriteSetChangeWriteTableItem is always null based on ts-sdk call. Would be great if it can be decoded and filled.

Motivation

Is your feature request related to a problem? Please describe you use case.

It's helpful to know what's inside the WriteTableItem without having to make an additional getTableItem call.

Additional context

Use this txn https://aptoscan.com/transaction/563060087#changes as an example. From aptoscan.com we easily tell the decoded data (see below).

However, when using ts-sdk to write a script (see below), the data field is always null

import { Aptos, AptosConfig, Network, WriteSetChange, WriteSetChangeWriteTableItem, isUserTransactionResponse } from "@aptos-labs/ts-sdk";

const aptos = new Aptos(new AptosConfig({ network: Network.MAINNET }));

main();

async function main() {
    // https://aptoscan.com/transaction/563060087
    const tx = await aptos.getTransactionByVersion({ledgerVersion: 563060087});
    if (isUserTransactionResponse(tx) && tx.success) {
        for (const change of tx.changes) {
            if (isWriteSetChangeWriteTableItem(change)) {
                console.log("change", JSON.stringify(change))
            }
        }
    }
}

export function isWriteSetChangeWriteTableItem(
  change: WriteSetChange,
): change is WriteSetChangeWriteTableItem {
  return "handle" in change && "value" in change;
}

running this script we get (note the null data field)
