remove coal cost scaling
一块煤产9点能源，一个军工消耗0.25+工厂数量×0.0225点能源。
把递增的部分去掉后36个军工只会花一块煤。
理论上兼容世间万物。
One unit of coal produces 9 units of energy.
One military factory consumes 0.25+number of factories*0.0225 units of energy.
Removing the incremental part, 36 mil factories will use only one unit of coal.
Should be compatible with any mod.
另外打个广告，关注架空模组灵钢协奏曲谢谢喵。Also please follow another mod I’m working on.
