Add Voicemeeter Command and Sensor support

[Levi--G]

This PR adds Voicemeeter support for the Hass.Agent

Only basic support is added, allows running VM macros and getting parameters as sensors. Once its possible to add more complicated setups i can do that easily.

Would you be able to provide me some test cases so I can grab those changes and have a real life test?
Any tips on voicementer installation and then some HASS.Agent test scenarios :D

Voicemeeter can be downloaded for free from https://voicemeeter.com/ , the standard will do for just testing. All you need then is to add some commands in hass.agent, for instance:
Mute mic: Strip[0].Mute=1
Set Mic to default: Strip[0].Gain=0,Strip[0].Mute=0

you can also add a sensor like this:
Strip[0].Mute
Strip[0].Gain

Then if you press the buttons while voicemeeter is running you can see the slider/mute button of the left-most channel change and you can also see any change of the slider in homeassistant as the sensor. You don't need to have an input or really set up voicemeeter to see the changes, but if you want to set it up there are some guides here: https://voicemeeter.com/user-guide-startup-the-first-steps-replace-the-windows-mixer-with-voicemeeter/

I think this is what you needed? If not let me know :)

Any chance of getting a review? ;)
If you need anything more let me know.
Thanks.

This took me way to long...
On windows as we speak and I'll start with the testing :D

Edit: the installer and flashing "Installing" give me 2002 virus vibes :D

Good news, and bad news :D

Overall everything seems to be working fine (at least to the level I was able to check - i.e basics) but we have one major issue, HASS.Agent crashes if the VoiceMeter is not installed.

I have other small questions/requests but let's leave them "for later" - my suggestion is to add a function to check, during manager initialisation if the appropriate dll files are there (+ maybe unify both native x86 and x64 classes?)
