Fryc's Parry (aka Sword Parry)

To those who look for 1.21: it will come a bit later To those who look for 1.20.2 (is someone even playing on this version?): it won't come, sorry

Changes:

• separate cooldown system:
  • cooldown is saved on player, not items
  • cooldown is shown as a small shield under your crosshair (position can be changed in client config)
  • axe attacks still apply cooldown on item that was used (configurable in other.json5)
• disarmed sets cooldown on items in main and off hand no matter what item types
• added parry indicator (disabled by default):
  • green means attack will be parried
  • yellow means attack will be blocked
  • red means you haven't started blocking yet (block delay)
• parry attributes are shown in tooltips (can be disabled in client config)
