## Feat. Add Support for Mysa AC-V1-1 Devices
### Overview
This PR aims to extend **mysa2mqtt** to support **Mysa AC-V1-1**
thermostats in addition to the existing baseboard models.
AC-V1 devices use different operating modes and fan modes, which
required updates to both mode translation and MQTT behavior.
Tested with `BB-V1-1` and `AC-V1-1`.
*Note: I'm no typescript expert so code might not look the best but is
fully tested*
### Key Changes
- Supports `cool`, `dry`, `fan_only`, and `auto` in addition to `off`
and `heat`.
- New fan modes: `auto`, `low`, `medium`, `high`, and `max`.
### Does not support yet
- Vertical swing
- Horizontal swing
### Technical stuff
`AC-V1-1` payload:
`"body":{"success":1,"type":2,"trig_src":3,"state":{"md":3,"sp":23.5,"lk":0,"ho":1,"br":100,"da":2,"fn":5,"ss":4,"ssh":12,"it":0}}}}`
Fan mode values: 1 = 'auto', 3 = 'low', 5 = 'medium', 7 = 'high', 8 =
'max'
**I named the value 8 max as I needed a 4th value but is not tied to
anything in HA or Mysa**
### Testing
