[+] Check: Infinite Stamina check (Sprinting) - fully lag-compensated. Might have issues with some mods, please test.
[+] Check: SpeedB - Another experimental check, not recommended to enable for now
[+] Check: MoveStateValidation - Not complete yet but this checks for spoofed movement states
[+] New Config option to configure the cooldown between setbacks. This avoids packet spam and random disconnects. I recommend leaving this at the default value, at least not below 20 (Unit is in client move packets).

[#] Fixed rare cases where lag compensation tasks could be skipped by missed packets
[#] More stable setbacks including a new cooldown option and now using teleport packets
[#] Fixed lots of Fly and Speed false flags regarding custom ApplyForce interactions and double jumps
[#] Fixed falses with rail-carts by excluding the checks for now
[#] A few other smaller bugfixes across all checks

I'm currently working on lag compensated entity tracking, for soon to come reach checks and other combat checks in the future. I'm also working on lag compensated world tracking to prevent noclip and fix certain fly bypasses, but it's unstable for now.
