reworked survival/waypoints.sc

[Rocka84]

Hi!
I updated the waypoints script and would like to offer my changes to the community.

Initially I wanted to fix/improve the rendering when tracking waypoints but ended up reworking the whole script.
The features are mostly the same but with some differences

• completely redone the rendering of tracked waypoints
  • draws a floating sphere in the direction of the destination and/or
  • show distance and directional arrows in the actionbar
• overhauled waypoint listing
  • by default filtered by the current dimension of the player, configurable
  • utf8 icons
• admin config and more player settings via commands
• general code cleanup and rearrangements
• tested with 1.21.3 and 1.21.5 with the latest available carpet versions
