Update to Python 3.13

[muriloSGomesDr]

Hello everyone, how are you?

I'm testing Python 3.12 and 3.13 with this library. And I want to inform you that with Python 3.12 it apparently works. In fact, I had already been using it with Python 3.10 and 3.11 without any problems. I believe it would be nice to update the README, so people can stay informed.

However, in Python 3.13 I received this error:

Traceback (most recent call last):
