Support extended tokens + expose token feature for library use

[beesaferoot]

I updated some sample tokens as they did not match the expected tokens which I verified using the original python library.

@dmohns You can confirm if the changes are accurate. Closes #10

Hey @beesaferoot

following up on my earlier comments. I think the issue was that we never actually had Extended Tokens in the test JSON 😅 I generated some using the legacy Library.

Could you add the JSON as per this PR: #34 to your PR? (Probably you can just cherry pick my commit) And see if this resolves this issue?

Hello @dmohns I got around this and updated the sample tokens from your PR.

Everything seems to be working as expected now (for standard and extended token generation).

Hey @beesaferoot

Thank you for your patience with this one 🫣 I got some more information about the issue I mentioned earlier.

The Test Tokens I generated originally, where created using the Legacy Python library. It looks like the library is actually not generating extended Tokens correctly, see EnAccess/OpenPAYGO-python#21

Let's merge your PR as it is

Using #35 We can cross check the implementation, will look into that next.

Thanks for merging 👍🏾
