fix: Improve a couple of things in MQTT sync from Teslamate

[cguedel]

Fixes #689

• parse boolean strings for is_climate_on, locked, sentry_mode
• add sync for plugged_in
• add sync for charge_port_door_open
• add sync for trunk_open
• add sync for frunk_open
• add sync for is_user_present
• add sync for is_preconditioning

Thanks. I think the test failure may be unrelated but there's some lint issues. Can you please address?

[cguedel]

Should be ok now I think, no idea about the tests though

Thanks for the fix!
There's a typo in the code here:

def cast_trunk_open(val: str) -> int:
    """Convert bool string to trunk/frunk open/close value."""
    return 255 if cast_bool(str) else 0

cast_bool(str) should be cast_bool(val)

[cguedel]

Sorry about that, I'll take care of today

No worries, thanks for supporting this great integration!
