My second datapack! Again pretty simple but original :)

Makes armor little bit more realistic.
How it works:
The more armor pieces player have, the slower will be his movement and attack speed.
1-10 armor = -1% of speed and -0.25% of attack speed for each piece
11-20 armor = -2% of speed and -0.25% of attack speed for each piece

Max debuff = -30% of speed and -5% of attack speed
