Add AudioSettings

Basic audio settings have been implemented in RaspberryIO:

• Set a specific volume level percentage.
• Set a specific volume level in decibels (dB)
• Mute an audio device.
• Consult audio device settings.

Users set an audio card, an audio device and an audio command to perform an audio action. Example of audio tasks:

await Pi.PiVolumeControl.SetVolumePercentage(85).ConfigureAwait(false);

await Pi.PiVolumeControl.SetVolumeByDecibels(-1.00f).ConfigureAwait(false);

The code above sets the volume level in two different formats: Percentage or Decibels.
The first method sets the volume on percentage (0% - 100%) and the second sets the volume level on decibels(dB) (-101.32dB - 4.00dB).

Users can consult the current audio settings by using the method GetState.
An example is shown below:

var currentState = await Pi.Audio.GetState().ConfigureAwait(false);
Console.WriteLine(currentState);

The same result can be achieved by setting the volume level to 0% or -9999.99dB.
