Create ReAutomated: Traces

Added

• Added default Traces for the Nether Quartz and Ancient Debris Nodes from Create ReAutomated 0.3.x. Both can now be tracked with the Trace Finder.
• Discovered Traces now keep a thinner, dimmer beam instead of disappearing, so walking through a beam no longer loses the marker. Mining the Trace block removes its beam.
• Added showDiscoveredTraceBeams and beamsRequireHeldFinder Finder config options.

Changed

• Create ReAutomated 0.3.1 or newer is now required.
• Beams are hidden while you stand within 8 blocks of their Trace and come back when you walk away.
• Beams now only render while a Trace Finder is held in the main hand or offhand. Set beamsRequireHeldFinder to false for the old behavior.
• Network protocol bumped to version 4: server and clients must update together.
• The tracePlacementDiagnostics config description now mentions the chat notice sent to operators.
