KNX Project to Home Assistant config converter

Utility tool to convert a KNX project into a Home Assistant configuration. It depends on xknxproject for parsing of the actual ETS project.

Concept

The configuration in ETS can be placed in the "comment" section for a group address.

```hassos
<entity_type>:
  <params>
```

To connect a ha-knx-light device type with a group address use the following comment:

```hassos
light:
  name: <name>
```

The address and state_address parameter are automatically set to be the GA address to which the comment belongs too.
