Electron不支持ipc傳遞Blob，會提示無法序列化錯誤

解決方法：將Blob轉(zhuǎn)換為Buffer再通過ipc傳遞

let reader = new FileReader()
reader.onload = function () {
    if (reader.readyState == 2) {
        let buffer = Buffer.from(reader.result);
        ipcRenderer.send('nesarc_common_notify', { buffer: buffer });
        console.log(`Saving ${JSON.stringify({ size: blob.size })}`)
    }
}
reader.readAsArrayBuffer(blob)
