feat: Detect when player is within map bounds

[zachthedev]

Issue

If there are multiple maps, the player shows up on the lowest priority map of the same dimension but not where the rendered part of chunks are.

Use case

A nether map with roof transparency and then another map that is only the roof and above (to showcase redstone builds, etc).

• Clicking on a player on a different map, will take the user to the correct map for viewing what they are working on

@TBlueF No worries! That totally makes sense. I had actually started on that approach to refactor this PR, but time got away from me. I plan to pick it back up sometime in the next week or so.

BlueMap has now implemented render-masks which this PR would need to be updated to. Additionally there should be a configuration to turn this behavior on and off.

I will close this for now due to inactivity, feel free to re-open if this is being updated :)
