Change default coordinates

[Jerska]

Hey there!

Thanks for this tool, it's awesome to be able to have such a map of our world! :)

The small pain point I have is because, in my server, we've moved to something like -8000, -2000, which means you have to dezoom quite a bit before seeing the map.

It's solvable by sharing the URL with the coordinates inside them, or having a redirect, but it would be great to be able to set the default coordinates via a flag at build time (or use the world spawn coordinates instead of (0,0), we've moved it with /setworldspawn).

You can probably edit the index.html file no load those coordinates by default.
