Authorizer is not exported

So, I just updated my Casbin.js version from 0.4.0 to 1.0.1 and I’ve run into the following error:

TS2305: Module '"/node_modules/casbin.js/lib"' has no exported member 'Authorizer'.

It seems that the Authorizer class is not being exported anymore. I looked into the docs (here in Github and in the Casbin website), and both still cites the Authorizer on how to use the lib.

Was the Authorizer removal by design or is this a bug?

Steps to reproduce the error

1. Simply install any version of Casbin after the version 0.4.0;
2. Try to import Authorizer, as noted in the docs:

	import { Authorizer } from 'casbin.js';

or

	import * as casbinjs from 'casbin.js';

	const authorizer = new casbinjs.Authorizer("manual")

Environment

I was able to reproduce this error in two different scenarios:

1. Using React with CRA
2. Using React with Vite

This error also persisted from the version 1.0.0-beta.1, from what I tested.
