Make farts and oxygen agent b more accessible

[Chomusuke]

For now Ill PR a fart canister to the in rotation maps. Feedback on the toxins layout would be appreciated.
(Note that the images show a different sprite then the regular green cans because I messed around locally. They will all be the regular green you are used to)

Atlas:
Moves the top left empty canister onto the 2 way connector and places puts a fart can in its place.

Donut2:
Moved the N2 cans to the right and put the farts in the top left.
Yes this one is meant to be somewhat of a pain to get out. You will have to move several cans out of or around the gas storage.

Donut3:
Given the existing compartments for the other types of cans I just put it by the purge valve.

Moved the right column of oxygen cans up and put the farts in the bottom right corner.

Nadir:
Nadir is not a plasma research station and does not have a traditional toxins but it is possible to create burns on it especially with constructible atmos.
Given that its not officially designed to handle burns I hid the can behind an already existing hidden wall near engineering.
I am considering to add an empty tank and mask or a destroyed air scrubber to it for a little bit of story but I am unsure on that
