Augmented state issues

[hllhll]

When AC is off, Certain platforms (in my case, google home connected to HomeAssistant) would allow changing temp, fan speed etc when AC is off.
HOWEVER, When AC is off, temp and mode displayed by the device is Auto, 25d. So if any changes happens after device is off, next ON (even physically) the device will come up as On, Auto, 25d.

This can be remidiated by 2 steps:

1. Augment the last known AC state when it was on. (Ignoring on/off state and current temp)
2. If last on state was not kown, prevent any changes to it before turning on.
   I think this would solve: Turning the device off with ha gui switches ac to auto next time #24 and Damper (TAC910) system closes when turning off or on the HVAC #22

The original problem seems to come from the device itself. When I reset the breaker for the AC, it defaults to 25 as well when turned on again. (Love love this UDP server you made, saved me so many headaches of airconet servers being offline and not being able to use the device)
