ASIO: open control panel

[Sin-tel]

Just putting this here for now so people know it is at least possible.

Will have to think about a proper API if we want to include this. (extension traits?) I would also be fine having this only exposed in asio-sys for now, but you'd need to expose driver internals if you want to use it from cpal.

Also, I had to modify the build script to get rid of linker errors, not sure what's up with that.
