switch to pipewire

I uninstalled pulseaudio, pulseaudio-bluetooth and pulseaudio-alsa
before running this. I think that is unnecessary and the pipewire-pulse
package will resolve any conflicts. But who knows.

For my audio needs, pipewire seems to be a drop-in replacement now. I
notice no difference.

Closes #95
