Removes roundstart singularity, adds roundstart supermatter, supermatter now collapes into singularity (#24447)

* Adds supermatter to box.
Adds orange pipes.
Makes the supermatter spawn a singulo.

* Added orange pipe manifolds.
Added a supermatter crystal and replaced the varedited shards on box and meta.
Added supermatter engine to metastation.

* Removed singulo from Deltastation.
Gave engineers access to some Deltastation atmos areas, including the engine.
Fixed some access bugs.

* Misc fixes.

* Fixed the roundstart reflectors being impossible to deconstruct.
Bunch chamber tweaks on meta.

* Poly now squawks about the supermatter engine instead of the singulo.
Radiation collectors are now half as efficient.
