Add locational voice chat range cut-off setting

#1491

[ruby0b]

Not sure if using 0 as a special value to disable the feature is idiomatic or if I should add a bool that enables/disables the cut-off being active.

As for the motivation for this feature: by default, you can basically still hear every player from anywhere on the map, they just get very quiet at some point which is probably not what most people want.

Does this also account for the "local origin" issue where anyone standing near 0,0,0 will be able to hear conversations at a much higher volume due to the speaking player being in the PAS but not the PVS?

[ruby0b]

Sorry, I don't know anything about that issue (didn't even know that was a thing). Would that affect distance calculations?
If not then I guess this would fix that since you're guaranteed not to hear anyone outside the given range.

It is more like it is a problem that frequently crops up with distance-cutoff because the issue becomes more apparent when the voice range is relatively small but the map is dense, I'm surprised you haven't had it come up.

Looks very good and i think 0 is fine for disabled 🙌

Thank you so much for improving this.

Looks good to me :)

using 0 to turn this is off is a good choice
