Simple Compass

Change Notes:

• Added Render Modes for Waypoint and Direction Indicators
  => Always, Never, When holding Compass (in Main- or Off-Hand)
  => Removed the Enabled Option: toggling everything to Never has the same result
• Fixed a few typos (just don't check what was wrong before :) )

Unless there is unexpected demand, this will be the last feature update available for 1.17, as most mods are now released for 1.18.
Use that version instead.
