Read item skill requirements from the cache template

validForSkills, isShield, the guard attack rating and the NPC vendor skill
filter read getItemSkillReq. Offline parity (p15d.py, 7586 rows): 0
differences. No template lists "Cloth" in item_skill_req and none has more
than one entry, so file order vs HashMap order is moot.

Value changes: none.
