Prefix the JSON file name

[justin-umesh]

Hi, I want to prefix the JSON file with custom value.

` async sendJSON(message: unknown, options: SqsMessageOptions = {}, jsonprefix): Promise { const messageBody = JSON.stringify(message); const msgSize = Buffer.byteLength(messageBody, 'utf-8');

    if ((msgSize > this.messageSizeThreshold && this.largePayloadThoughS3) || this.allPayloadThoughS3) {
        const payloadId = uuid();
        const payloadKey = `${jsonprefix}${payloadId}.json`;`
