fix crash on pulseaudio

[Vendicated]

the current implementation segfaults on pulseaudio because it tries to call pipewire methods, which, for obvious reason, are not actually available:

Message: Process 486613 (electron) of user 1000 dumped core.
         
         Stack trace of thread 487173:
         #0  0x00007f4aa36f9404 pw_proxy_get_bound_id (libpipewire-0.3.so.0 + 0x78404)

this pr fixes it by first manually dlopening libpipewire to check if it's installed

i don't know if this is the best method to do so, so feel free to close this pr if there's a better method

As pipewire-pulse exists, I'd prefer if we first use the pulseaudio api to check the name of the server, if it does not contain "(pipewire)" we throw (using pa_server_info)

That way we also catch users that have pipewire installed but don't use it as their audio server

Also, will we provide pre-built binaries for the addon or will we just pull it in through npm

If the latter is the case, the user will need pipewire installed otherwise it might not compile (so we might just tell the user to install pipewire - just having it installed won't force them to use it)
