The `spell_group_stack_rules` table
Table defines if auras in one spell_group can't stack with each other.
Notes: The table doesn't affect persistent area auras stacking or passive auras stacking (they can stack always) or spells belonging to same spell_rank (they are always subject of SPELL_GROUP_STACK_RULE_EXCLUSIVE rule)
