Standalone function

The standalone function version of this method:
import { OpenRouterCore } from "@openrouter/sdk/core.js";
import { sttCreateTranscription } from "@openrouter/sdk/funcs/sttCreateTranscription.js";

// Use `OpenRouterCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const openRouter = new OpenRouterCore({
  httpReferer: "<value>",
  appTitle: "<value>",
  appCategories: "<value>",
  apiKey: process.env["OPENROUTER_API_KEY"] ?? "",
});

async function run() {
  const res = await sttCreateTranscription(openRouter, {
    sttRequest: {
      inputAudio: {
        data: "UklGRiQA...",
        format: "wav",
