AmmoType to expose missing fields

[Muppet9010]

At present the runtime AmmoType object doesn't expose some fields, this makes calculating via scripting the true runtime values of for a specific ammo in a weapon impossible, i.e. max range of a atomic-bomb ammo in a rocket-launcher, as atomic-rocket has a range_modifier of 1.5

The fields I see missing look to be the modifier fields:

• range_modifier
  cooldown_modifier
  consumption_modifier

AmmoType being obtained at runtime from its prototype via: https://lua-api.factorio.com/latest/Lua ... _ammo_type
