Mod Support: Support custom sound events

[Kaffeine]

Feature request: support a netmsg to play a custom sound (e.g. embedded into the map or downloaded via #7296).

We'd want to play a sound at a certain position (like NETEVENTTYPE_SOUNDWORLD does) or globally, like it does NETEVENTTYPE_SOUNDGLOBAL.

Right now most of the mods have to use flag captured/drop/returned global sounds to announce important events, and re-use default sounds for our custom events. The biggest issue is that there is no sound which would fit certain use-cases. E.g. I need a short alarm/warning sound to warn the player about a building destruction (similar to a bomb timer 'beep' sound). I'd also like to use custom sounds for the many custom weapons/objects.

I think this does not strictly require #7296 as we can use the map embedded sounds for now. I'm yet to come with a detailed plan (can take days), feel free to suggest it.

Would it make sense to reference the sounds by SHA256 or we'd prefer short string names or something else?

The server can send an indexed list of custom sounds and use those indices instead of sha/names. Another benefit is that (later) the client can use the list to download the missing assets (#7296).

All of that is possible using #7042 (comment)
But again, no official answer from ddnet, so...

Some forks have server and client side LUA support but there is no code implementing a communication channel between the server-client scripts. Having that in DDNet is a too distant, complex and very questionable goal.

Do you mean that you'd prefer to have it this way: server-side LUA sends custom event to the client-side LUA and the client script parse it and plays the sound?
