Skodaconnect

The library have a reworked login function with extended debugging and functionality to login using native Skoda API instead of only VW-Group.

Added version to manifest.

Changes to library:
* Added more debug logs for login method
* Some cleanup and de-branding of code and comments
* Minor tweaks for attributes causing errors (combustion_range amongst others).

Bumped version to reflect underlying library.
- Fix where pre-heater actions wasn't working
- Added value validation for error-prone vehicle attributes
- Added log messages for login error codes, throttled and invalid credentials.

A service call is added to support setting the charger maximum current.
So far only two values supported, maximum and reduced (252=reduced, 254=maximum) for PHEV (?) only.
To get this working with BEV vehicles a debug log is needed to determine supported values.

The underlying library has undergone major code changes and there might be some breaking changes. Be sure to read the readme and backup all data.
- Valid services check is added
- Token handling is added, verification at login, validate before requests and revoke on shutdown/logout
- Some enitites have changed names, some have changed type
- device tracker should be fixed, position is now "not_home" when car is moving. This might break the automation example in README.
- Requests handling is improved and status per section is added. Requests now trigger immediate refresh in hass gui
- Added config option for enabling/disabling comprehensive debug of raw response data
- Code cleanup
- Inverted data for service days and distance
- Disabled unused service (departure timers)
- Added token revocation on logout
