Add support for Tfiac Climate component (#21823)

## Description:

Add support for AC-models that follows the Tfiac protocol. Built together with @mellado.

**Pull request in [home-assistant.io](https://github.com/home-assistant/home-assistant.io) with documentation (if applicable):** home-assistant/home-assistant.io#8910

## Example entry for `configuration.yaml` (if applicable):
```yaml
climate:
   platform: tfiac
   host: 192.168.10.26
```

## Checklist:
  - [x] The code change is tested and works locally.
  - [x] Local tests pass with `tox`. **Your PR cannot be merged unless tests pass**
  - [x] There is no commented out code in this PR.

If user exposed functionality or configuration variables are added/changed:
  - [x] Documentation added/updated in [home-assistant.io](https://github.com/home-assistant/home-assistant.io)

If the code communicates with devices, web services, or third-party tools:
