Subject: [PATCH] Update export styles for ESM compatibility

Node.js's ESM-to-CJS interoperability only supports a limited subset of exports.  (See [cjs-module-lexer](https://github.com/nodejs/cjs-module-lexer/blob/main/README.md) for details.)  By switching to one of the supported styles, ESM code can use named imports from jsonwebtoken.

To demonstrate, create a `test.mjs`:

```js
// Within the jsonwebtoken directory:
import { verify } from './index.js';
// Or importing from an installed jsonwebtoken package:
import { verify } from 'jsonwebtoken';
verify('a', 'a');
```

Without this change:

```
import { verify } from './index.js';
         ^^^^^^
SyntaxError: Named export 'verify' not found. The requested module './index.js' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:
```

With this change: Successful execution (in this case, a "jwt malformed" error).

This issue is further documented as the ["Named Exports"](https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/NamedExports.md) error on [Are the Types Wrong](https://arethetypeswrong.github.io/?p=jsonwebtoken%409.0.2).

Fixes #963, #875
