ERR_REQUIRE_ESM when running the usage example from repository's readme.md #102
Description
Describe the bug
When running the basic usage example from repository's readme, I'm getting following error:
internal/modules/cjs/loader.js:1085
throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
^
Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: D:\workspace\node-sspi-exp3\node_modules\node-fetch\src\index.js
require() of ES modules is not supported.
require() of D:\workspace\node-sspi-exp3\node_modules\node-fetch\src\index.js from D:\workspace\node-sspi-exp3\node_modules\node-expose-sspi\dist\sso\client.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from D:\workspace\node-sspi-exp3\node_modules\node-fetch\package.json.

To Reproduce
The same steps and flow as in readme:
mkdir myproject
cd myproject
npm init -y
npm i express
npm i node-expose-sspi
...
node server.js
server.js:
const express = require('express');
const { sso } = require('node-expose-sspi');
const app = express();
app.use(sso.auth());
app.use((req, res, next) => {
res.json({
sso: req.sso,
});
});
app.listen(3000, () => console.log('Server started on port 3000'));
Expected behavior
Run without errors.
