Lightning Grim Anticheat

• Mark LineOfSightPlace as experimental
• Make Inventory checks support/respect nosetback permissions
• Fix Entity tracker for <1.16.2
  • Note that Reach, HitboxMiss, and HitboxEntities may have a known false issue with changing an entity scales while they are being attacked for less than a tick.
  • Significantly improved false rate of HitboxEntities, lucky cheaters may escpae momentary detection but long-term will be found. Currently thought to be mathematically impossible to false.
• Added /grim hitboxdebug command that sends hitbox data to clients when attacking an entity, can and will be rendered by a client side mod like https://modrinth.com/mod/lightning-debug v1.1 and newer.

• Added a /grim history command that shows you historical flags players have triggered
• Split Reach into 4 seperate checks
  • Reach - checks if they hit from too far (known to be unfalsable)
  • HitboxMiss - checks if player missed the target entity hitbox (very rarely falses)
  • HitboxBlock - checks if a player hit an entity through blocks (no known falses)
  • HitboxEntities - checks if a player hit an entity through another entity - (falses uncommonly)
• Improved HitboxEntities to check through entities in Vanilla's iteration order, reducing false rate significantly especially in swarms of mobs or team fights. Note that this check is disabled by default.

• Fixed InventoryD not working due to upstream changes to simulation engine movement data.

• Hotfix loading Post check twice causing error
