Fluid Box 2.1.22 Compat Shim

Factorio 2.1.22 (experimental) removed FluidBox::minimum_temperature and
FluidBox::maximum_temperature. Mods that still set these properties (often
inherited from older prototype copies) fail to load with errors such as:

Error while loading entity prototype "steam-engine" (generator):
FluidBox minimum_temperature and maximum_temperature have been removed.
Similar properties have been added to most machine prototypes.

This mod is a generic shim: it does not target specific mods. After all
other mods have run their data stages, it scans every entity prototype in
data.raw and:

1. Migrates fluid-box minimum_temperature / maximum_temperature to the
   new replacement properties on the owning machine:
2. boiler, generator, fusion-generator, fusion-reactor,
   mining-drill → prototype-level minimum_input_temperature /
   maximum_input_temperature
3. entities with a fluid energy_source →
   energy_source.minimum_input_temperature / maximum_input_temperature
4. thruster → minimum/maximum_fuel_temperature and
   minimum/maximum_oxidizer_temperature
5. output-only fluid boxes have no replacement; the removed keys are deleted.
6. Deletes any leftover removed keys from fluid boxes so prototypes load.
7. Converts fluid energy-source maximum_temperature = 0 (old "unlimited")
   to nil (new "unlimited").

Known affected mods (migrations are logged to the game log):

• planet-muluna (sets steam-engine/steam-turbine fluid box temperature,
  oxidized boiler, cryolab, recycling steam turbine)
• quality-seeds (fluid energy source on the space cultivator)
• corrundum (red steam engine)
• fluid-nutrients

Optional dependencies on these mods are declared only for load ordering, so
the shim always runs after they modify prototypes. Any other mod is covered
generically as long as it sets the properties during data/data-updates stage.

Notes / limitations

• The shim runs in data-final-fixes. If a broken mod sets these properties
  in its own data-final-fixes stage and happens to load after this mod, add
  an optional dependency to this mod's info.json to fix ordering:
  "? <that-mod-name>".
• Only the first fluid box's value migrates when a machine has several input
  boxes that each specify a temperature (later duplicates are dropped).
• Runtime (control stage) code in other mods that reads
  fluid_box.minimum_temperature off Lua prototypes will now see nil; that
  is out of scope for a data-stage shim.
