Setter of Access token

[anshulg954]

Change Description

Try to be precise. You can additionally add comments to your PR, this might help the reviewer a lot.
Enhancement to set the access token if the user already has it.

• The user can now set the token via init(access_token="access_token"). If the access token is valid we will use it, otherwise the pre-existing prompting will continue.
• Also the user can view his/her token by get_token() directly.
• Additional Information regarding access token can also be found in all the above functionalities.
• Test cases have been updated and added.
• Readme.md has been updated as per functionality.
• Fixed Issues in resetting token. Earlier it was just deleting the file but not clearing the existing cache and was not updating the existing config.
• Also gave a temporary fix for reverify email() which has been fixed thoroughly in hashing PR.

If you used new dependencies: Did you add them to requirements.txt?

Thanks for the work!

I think we could add one more feature, where the user can set the token directly without having to go through the prompting. One example is, tabpfn.init(access_token='blablabla').

This is a misunderstaning in how the access token is sued. We only want to set the access token using a functional interface, so by calling tabpfn.set_token(...) not using the prompt interface. The token is useful if you want to programatically login, so I think we don't need any new code, but only add to the README doc how to login using the token

Can you add some test cases? Also perhaps a demonstration on this work.

P.S: When you create a PR, would be nice to provide the reviewer an idea/demonstration of the new workflow.

Hi Liam!
I did not think it as of a major change the first time I created this PR as it was a few lines of change. However, later forgot to modify the description about the changes. Sincere apologies for the same.

As per your comments, I have updated the code and added test cases.

no reply, changes done

I think this PR does not have much new stuff compared to the current main. I would close this, ok? Sorry about this
