Add more gas tanks to suit lockers.

About the PR

Adds a nitrogen tank to all suit lockers.
Adds extended oxygen and nitrogen tanks to engi, atmos, and security suit lockers.
Adds double extended emergency oxygen and nitrogen tanks to command suit lockers.

Why / Balance

The nitrogen should be self explanetory, theres plenty of species which use nitrogen now and they should be considered.
As for the extended for engi atmos and sec, they will need to use space semi-often, engi and atmos need it regularly, while security will need it for extended periods of time while their backslot is clear for a weapon
Heads also need space surprisingly often, with a lot of them having better things to put on their back, and them having to go to EVA in some maps or scrounge through maints in ones that dont have them mapped to get better pocket tanks feels wrong. I feel like they should get these roundstart, especially since some maps have them mapped while all of them can have them spawn in maints.

I believe maintainers specifically want to avoid doing this because of the entity bloat it introduces but I could be wrong

I feel like its not that bad, and it doesnt make sense to ignore the nitrogen breathing species for this reason.

the conclusion every time nitrogen tanks are added wherever oxygen tanks are is "it makes it so that there aren't any differences (downsides) between the species" but you're left with extra nitrogen tanks everywhere for the very few pure-nitrogen breathing species on station

this reasoning was used in #25660 but now that we have vox, which can only breathe nitrogen, unlike slimes which can get by on a regular air mix, we should revisit readding them to at least a few places, though i agree that just putting them anywhere oxygen tanks are is too bloaty

For the record, theres 2 main parts to this PR: Adding the extended & double tanks, and the nitrogen. If maintainers want to deny one but accept the other, let me know and ill update the PR accordingly.

Hey, we had a vote among the maintainers and the result was to close this PR. The main reason stated in the discussion was that N2 is supposed to be scarce on purpose to not make the difference between species trivial.
For department heads we want them to focus on doing their job and not go and do everything themselves. This addition would further motivate them to go off into space.
Thank you for your contribution.
