Butane should spawn more often

Is your feature request related to a problem? Please describe.

Currently, butane comes in 3 forms in the game. Either from butane lighters, which cannot be unloaded, from cans of butane, which can be looted from various places, including houses (though they are fairly rare), and tanks of butane, which are stupidly rare, only dropping from FEMA camps and hazardous waste sarcophagi. While butane is not phenomenally useful, mostly being only used as fuel, it is also required currently to use the essential oil extraction system.

Solution you would like.

Butane is not particular rare, and should have a few more spawn locations, such as hardware stores, outdoorsman stores (it can be used as a fuel for grills), or potentially gas stations. If tanks of pressurized butane aren't suitable for those locations, they would likely be more suitable to be added to the lab spawn pool.

Additionally, if possible, there could be extra devices that use butane, such as camping stoves or standing grills, to justify them appearing in more places.

Describe alternatives you have considered.
