construct_signature returns different values on Windows and Linux

[nicolaslazo]

gpsoauth.perform_master_login always returns BadAuthentication on Linux (Python 3.10.6) but is able to log in properly on Windows (Python 3.10.9) using the package version currently hosted on main. This is because the auth request payload contains a different EncryptedPasswd even if I put in the exact same credentials

If you have a chance can you double check that each platform returns the same ciphertext each time? It'd be surprising to me if there wasn't some kind of salt or nonce involved in one of the steps; it might be expected to get a different result each time.

I guess I'll reuse this issue to track #48 (comment), where stripping the ciphertext fixed things on linux.
