Breaking down Matrix's scaffold checks.

[mems]

From my experience with matrix, I've kinda learned a lot from these checks, so let's go.

Some of them might be wrong.

Type A: Pitch or Yaw
Type B: Yaw or Pitch 
Type C: Delay 1 (Either triggered by SafeWalk/SpeedModifier or lack of extra speed (S+D or S+A) while placing blocks 
Type D: Downward placement
Type E: Where you look at the block 1 
Type F: Eagle 1 
Type G: Eagle 2 
Type H: Placing block using illegal way (when xzRange is 0.8+)
Type I: AutoBlock Spoof 1 (Can be triggered only when PacketInput is not being sended)
Type J: AutoBlock Spoof 2 (Can be triggered only when PacketInput is not being sended) 
Type K: Instant turn 1 
Type L: AutoBlock Spoof 3 (Fast switching slots in hotbar)
Type M: Instant turn 2 
Type N: Event state POST (Placetiming Post) (PacketPlayer is being sended AFTER block placing) 
Type O: Delay 2 (Either distance from player to block or player's eyes to block) 
Type P: No check ? as of now (3/17/2021) 
Type Q: Where you look at the block 2 
Type R: Where you look at the block 3 (yrange for LiquidBounce, Y vector value for other clients) 
Type S: Possible Rotation Strafe while placing blocks 
Type T: Where you look at the block 4 (Enhanced edition) 
Type U/V/W/X/Y/Z: No check ? as of now (3/17/2021)

Might be useful for some folks out there who might be trying to bypass Matrix.

EDIT: Type N/J/I/L/H further explanations thanks to IdkWhoMe.

@mems As a happy deobfuscator of the matrix source, I can understand your observations, yet not all of these detection methods were correct. Well done though.
