Audio exclusive mode

[s-hadinger]

Description:

Implement audio exclusive mode, when In and Out share a common GPIO and full-duplex is not supported (for ex PDM).

In exclusive mode, switching for Output and Input requires to uninstall and resinstall the drivers. This is the case for M5Stack Core2, or M5Stack Atom Echo.
