Feat: update ERT sprites (#629)

# Описание

Ультимативное обновление Пауэр Рейнджеров. Теперь их стандартная броня
не кринж и в ней даже не стыдно выезжать на Сьерру. Спрайты от @honkemo.
Дополнительно им были добавлены балаклавы, противогазы заменены на
SWAT-версию. Была изменена униформа, добавлены особые ЕРТ-патчи,
заменены аксессуары, обозначающие специализацию, на свои собственные.

## Скриншоты
