[Temp beta] Clean Pathfinding 2 for RimWorld

This is a beta build for the next version of Clean Pathfinding. It will be taken down once it looks stable and made available on the main branch.

• Net gain performance: Through a number of optimizations described below, this mod is now net-positive on performance.
  
  
• Doorpathing: Allows you to designate some doors as having a higher perceived pathing cost than others. This can help prevent pawns from walking through sensitive rooms such as bedrooms or freezers, or using the non-main entrance.
  
  
• Major optimizations: As well as applying new optimizations to the cost adjuster, its tendency to be negatively impacted by other mods has been resolved.
  
  
• Optimized colliders: An optional patch to optimize vanilla's pawn collider code (pawns bumping into other pawns). Works the same as before, just on a smarter logic loop.
  
  
• Wander tuning: Adjust how often wandering pawns (including animals and wildlife) wander from spot to spot, allowing performance starved users to tone down their AI costs.
  
  
• Dialed in defaults: The default values have been finely tuned for performance, and the way road attraction works has been changed to be more versatile.
