Count inventory-knockback-cancels as hits

[AlexKnauth]

• Count inventory-knockback-cancels as hits
  • It currently counts some, but not all. Around 60%: when I get hit with 10 inventory-knockback-cancels in a row, it counts 5, 6, 7, or 8 of those (8 may have been an outlier, but 5 was not).
• Only count an inventory-knockback-cancel as 1 hit
  • In that ~60% of cases where it detects recoiling during an IKC, make sure it doesn't count that as a 2nd hit
• Count 2 hazard hits in a row as 2 hits
• Don't double-count normal knockback hits
• Don't double-count hazard respawn hits
• Count a normal knockback wombo-combo into hazard as 2 hits
• Count an inventory-knockback-cancel wombo-combo into hazard as 2 hits
• Count a triple wombo-combo of normal, hazard, normal as 3 hits
• Count a triple wombo-combo of normal, hazard, inventory-knockback-cancel as 3 hits
