add ash storms to lavaland

[deltanedas]

About the PR

every 5-10 minutes, an ash storm will kick up. for 1-2 minutes it will do 4 heat dps to any mob exposed to the storm (except for ashwalkers)

added ashwalker mob, theres no spawns or anything but they can tolerate the low oxygen and ash storms

Why / Balance

tg parity, creates some danger to straying too far from the base for too long
bluespace shelter capsules soon should you get trolled

it only damages living and crit mobs, so you wont get 5000 burn from dying outside

Technical details

• for ashwalkers, added SaturationLoss to LungComponent. can be used to change how harpies breathe in the future
• added WeatherScheduler which cycles a set of weather stages for a map
• WeatherPrototype can now define damage which is applied if you are on a tile with weather effects

Media

based urist mcash vs cringe uristmcscales

Requirements

• I have tested all added content and changes.
• I have added media to this PR or it does not require an ingame showcase.

Couldn't the weather scheduler be used to give glacier blizzards?

[deltanedas]

If you are adding ashwalker, you need to also add this.

ashwalker doesnt have a funny accent in ss13 it just speaks unathi
