Feature equip item

[PaulQbFeng]

My proposal for item handling

• Change champion stats structure. All stats have same name defined in glossary.

  self.orig_base_stats --> for basic champion stats
  self.item_stats --> for item stats
  self.orig_bonus_stat --> for bonus stats (item + runes)

• Can init a champion with a list of items defined in ALL_ITEM_STATS
• can equip dynamically an item with equip_item
• I tested ahri lvl 4 with cloth armor, pick axe, long sword, bf autoattack a dummy (see tests/test_champion.py)

I believe we can improve this solution by creating a Stat class and creating a magic method add so we could add stat class between them like self.bonus_stats = self.item_stats + self.rune_stats

Still need to test auto attack with a setup with armor pen, letha etc

[PaulQbFeng]

all champions should have in theory

• orig_base_stats with champion base stats
• orig_bonus_stats computed from items + runes + others
• base_stats that can evolve during a fight
• bonus_stats that can evolve during a fight

the last 2 can be altered when running auto_attack or spell_Q (yet to be created)

BaseChampion should have a method reinitialize_stats /bonus stats
