The vite+vue3 project does not support running on browsers below Chrome 80 version

What happened?

The vite+vue3 project does not support running on browsers below Chrome 80 version. Chrome 80 version only began to support modular import of workers.

The following code is invalid:

// For Vite:
import IMWorker from './worker?worker';
worker = new IMWorker();

// This method cannot use modular './worker.js
// worker = new Worker(new URL('./worker.js', import.meta.url));

open-im-sdk-wasm/lib/api/worker.js, uses modular import syntax, which is not supported in Chrome 80 worker. Unless manually escaped as es5. Expect SDK to perform ES5 conversion instead of users converting this worker

// open-im-sdk-wasm/lib/api/worker.js
import { RPC, RPCMessageEvent } from 'rpc-shooter';
....

What did you expect to happen?

Expect SDK to perform ES5 conversion instead of users converting this worker, Compatible with versions below Chrome80

How can we reproduce it (as minimally and precisely as possible)?
