Updates artillery turrets and artillery wagons so their automatic range equals
their previous manual range. Each artillery prototype receives its own gun copy,
so entities sharing a gun can retain different range multipliers.

Supports Factorio 2.1.23+. Krastorio 2 and Space Exploration are optional;
when installed, this mod applies its changes after their data-final-fixes.
Artillery prototypes must exist when this mod's data-final-fixes runs.
The mod does not enable automatic firing if another mod has disabled it.

Working artillery range behavior has been confirmed by the user in Factorio 2.1.23.
