China login

[Yixi]

Proposed change

Add a new nonce algorithm for the China region login, automatically complete the login graphic verification code, restore the login function for the China region, and update the refresh token method.

Type of change

• [x] Bugfix (non-breaking change which fixes an issue)
• [ ] New feature (which adds functionality to this library)
• [ ] Breaking change (fix/feature causing existing functionality to break)
• [ ] Code quality improvements to existing code or addition of tests

Additional information

Due to the public disclosure of the x-login-nonce algorithm in the Chinese region, the logic has been added to the library. Currently, password login requires a graphical captcha.

The solution we have incorporated allows for automatic bypassing of the graphical captcha obtained from https://gitee.com/cvnc/BMW/blob/master/lib/BMWLogin.js

The refresh token also needs to be included in the header with the x-login-nonce encoded using gcid.

To make the refresh token work, we will need to store gcid in the HA registry as well.
