Types for the `OAuth2Server` class does not include the `options` property

[wille]

Describe the bug

If you try to access the options set on a OAuth2Server instance when using TypeScript you'll get build errors.

The property exists on the class, just not in the type definition of the class.

To Reproduce

const options = { model } 
const server = new OAuth2Server(options)
server.options // Property 'options' does not exist on type 'OAuth2Server'. ts(2339)

Expected behavior

I'm building a library based on this project where I need to properly access options set on the provided OAuth2Server instance

Thank you @wille it is merged and will get out with the next release. Before that I'd like to ask you, if you already got similar issues with #368 and #367 during your library build?

[wille]

Didn't have the #368 problem yet but it is valid and should be fixed, but in my case I'm picking the client details from the client param when using saveToken.

#367 is valid but inner errors should be set on Error.cause https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error/cause
