[READY] Replaces sleepers with stasis beds (Lifeform Stasis Unit) (#43075)

* Adds stasis beds

Needs sprites, using placeholder ones

* Adds stasis beds to techwebs
Cryostasis Technology

* Adds sprites for stasis bed

* Stasis beds support economy/ancap

* Stasis bed can be deconstructed

* Stasis bed requires cable coil

* New stasis bed sprites by @Kmc2000

Made by Kmc2000 <bluekorben2000@yahoo.com>
Not currently functional

* Add unique to SSvis_overlay.add_vis_overlay

will return the overlay object itself and not reuse it

* Make stasis bed art function

can enable/disable with alt click
makes sounds when powering up/down

* The tubes go over the mob now

* Remove sleepers from techweb tree

* Fix stasis bed lying

* Modified stasis bed build requirements

* Survival pod version of stasis bed

Map spawned sleepers delete their circuit boards
Added stasis beds to 'doctors' phobia
NanoMed for survival pod which is always free, not refillable

* Replace sleepers with stasis beds on all station maps

removed all sleeper machine boards from maps
one sleeper machine board intentionally left alone in oldstation

* Fix stasis bed tube overlay capturing clicks

Give power up and down noise freq variation

* Remove stat check from living Life

* Remove vis overlay assertions from stasis bed
