Save successfully login sessions, re-use them next time + small code cleanup

[Arecsu]

Implemented a new class: EzvizSessionManager.

• It manages persistent token and session data on disk
• Uses sane default config locations across Linux, Windows and macOS
• If EzvizClient email + api_url does not coincide with saved token, it will attempt to login again.
• Config dir can change via arguments

Small code cleanup:

• Using new match case in _login
• Added a new error code for wrong username and password
• Replacing initial call of client.login() with client.start(). Name and logic should make more sense now that we have persistent login.

I did this in fear of calling login API endpoints to Ezviz so many times that it might break something. It also saves a potential API call by skipping the login process if there's a saved session. Not that much but feels good :)

Hi @Arecsu,

The original pypi package maintainer is no longer available to add a verified email address. I have decided to move this project to a new github repository with a corresponding pypi package.

Could you open a new pull request? Sorry for the extra effort but this is required otherwise we won't be able to do new pypi releases.
