    loadout slots are additionally purchased slots only
    1 slot per mastery rank is automatically given above mr10, without database needing to save the mastery slots
    extra = everything above the base + 2 slots (e.g. for warframes)
    new slot = extra + 1 and slots +1
    using slot = slots -1, except for when purchased with platinum, then slots are included in price

    e.g. number of frames:
    19 slots, 71 extra
    = 71 - 19 + 2 = 54
    19 actually available slots in ingame inventory = 17 extra + 2 Base (base amount depends on slot) (+ 1 for every mastery rank above 10)
    number of frames = extra - slots + 2
