Migrate BauSystem to the new TechHider and remove the legacy TechHider

The new TechHider registers a permanent global filter, so BauSystem now uses a single BauTechHider that combines the hiding rules of the spectator techhider, /techhider and /xray per player. To support the different obfuscation blocks of these rules, ForPlayer now provides the obfuscation block per position. The ChunkHider now also checks single valued chunk sections, which were sent unfiltered before, and recalculates their block count if they change. Unhandled packet types are logged once; statistics, debug samples and ping responses are passed through. The legacy TechHider and its access widener entries are removed.
