Allow JSON recipe format for Combustion Engine fuel

[pliant coral]

I wanted to allow combustion engines to use oils from Immersive Petroleum/PneumaticCraft, but I realized it was hardcoded.

its not

add the custom fuel tasg

tag*

[pliant coral]

oh interesting

didn't know that existed

[ripe steeple]

ig it does

¯_(ツ)_/¯

[pliant coral]

but what about fuel power

[ripe steeple]

its like vs_clockwork:stale etc etc

you would have to ask a dev for specific tags

[pliant coral]

what if

they added tags that work like
vs_clockwork:engine_fuel/(number)
and based on the number it changes the speed

i still believe json format is easier tbh

[ripe steeple]

but its not just for combustion engine

and that would be redundant

and janky
