Locator Bar should track loadstones

The locator bar is great for multiplayer, but is kind of useless for single player. This idea aims to change that!

The idea is that if you have a loadstone with a loadstone compass linked to it in your inventory, then on the locator bar it should show the locations of the loadstones. You might be able to dye loadstones (or make them out of different stone types or something along those lines) to make them look different on the locator bar. It'd be a really nice touch to make navigating around without F3 much easier and more streamlined.

Plus this fits with the loadstones being much more accessible after 1.21.5, making navigating structures much more convenient.

As for how it would work in multiplayer I suggest a toggle in settings, to switch the bar (for the client only, this wouldn't affect other players) from Tracks Players, Tracks Loadstones, or Off. That way players who don't want the locator bar to replace the XP bar don't have to have it on!
