Kimetsunoyaiba Tweaks

This update is entirely untested, so I have no idea if any of this works, if this breaks your game then go back to 1.6.45

• Added waypoint to return to Kanata and Kiriya after final selection completes
• Added killing intent potion effect
  • Each level of killing intent increases attack damage by 2%
  • Getting kills increases level and duration
    • Killing demons during final selection and during demon raids and killing demon slayers during demon slayer raids will increase effect level and duration
• Buffed Muichiro FP
• Nerfed Kanroji
• Fixed the issue where demon slayer entities use breathing forms they aren't supposed to use (like moon breathing slayers using kokushibo forms)
• Added a portal to return back to the overworld after final selection
• Added armor points to muichiro fp uniform chestplate and to all the boots
