Updated a lot of stuff

[DerDaku]

I've done quite a bit of work in the last few weeks to improve this project:

• Updated the mdns library so we can handle mdns service updates when IPs of Airplay devices change, etc.
• Updated the bluetooth library so it works again with Node 20
• I personally don't need PCM Input/Output so I disabled it and added an option to enable it using an ENV variable
• Added support for stereo paired Homepods including ones paired to Apple TVs as default TV speakers. They only appear as one Airplay Output now.
• Increased height of output selection in browser so it can show more than 4 devices at once on desktop

Hi @DerDaku,

Thank you for your contributions to this project i just discovered! I'll soon have a home pod and might test out your improvements .

Regarding the commit where @afaden mentioned the potential for using Airplay 2 with a snippet provided instead of the current code. However, it seems there were some challenges encountered along the way.

Have you had the chance to test it out? If yes, are you able to establish an Airplay 2 connection without any issues? If not, I'm curious if your edits inadvertently addressed the problems @afaden encountered.

Hi @ThomazPom

I actually did not test AirPlay 2 support, as I didn't even know the lib supported it.
I will test it over the weekend and enable it in my fork if it works.

Thanks for pointing it out.

Hi @DerDaku
I've conducted some testing with devices other than a HomePod, as I don't have one. It connects successfully to emulated Airplay 1 devices like Shairport4w and Reflector 4.

However, the directive "airplay2: true" is mandatory for it to connect to my LG C9, which features AirPlay 2 connectivity.
By now I'm investigating another issue with the bluetooth input stream, as babelpod fails to capture it.

I've rolled most of these changes into my own heavily improved fork at benlachman#5

Note that I did swap the PCM env variable to preserve backward compatibility.
