ModelDescription breaks Home Assistant topic structure

Hi @AirBeeSee,

the last release (v12) breaks the HA topic structure, at least for certain models. In the case of my Fiat 500e the ModelDescription equals Neuer 500 which contains a space. This breaks the topic structure and mqtt discovery of the device/entity fails:

What about using your haDevice.Name instead and replace not allowed characters to be safe here?
