Disable rotating for special characters

Once special characters are rotated, they become illegible. So I added the ability to disable rotation of all text characters and disable rotation of special characters anyway.

Okay, if you think there might be a problem with type hints, let's delete them.

I think they could be added to the whole package, maybe?

This is an advanced feature. I'd like to make image captcha the ability to add character by character, in this way, developers can control each character themselves.
