B1CustomizedRelationshipLevel

• Initial relationship level between two customized characters, chosen in the CAZ family tree editor.
  * Used by both entry points that open that editor: Create (new family) and AddFamilyMember.
  
  Level is the -3~+3 step defined by the RelationshipCondition table; it is converted to a float stat
  * value only when the characters are registered (B2RelationshipHelper::ApplyCustomizedRelationshipLevels).
  
  FamilyRelationships 와 별개의 배열인 이유: 그 배열은 가계도를 세우기 위한 최소 연결 지시서라
  * 부모 체인으로 재현되는 관계(부모를 공유하는 형제, 조부모-손자)나 관계 종류가 아예 없는 동거인은
  * 항목을 갖지 않는다. 그 조합들도 친밀도는 지정할 수 있어야 하므로 따로 담는다.
  * 저장은 FamilyRelationships 와 동일하게 양쪽 구성원에 미러링한다.
