Supermatter cascade round-end (#66659)

This PR adds the resonance cascade to the SM (idea ported from vg but with total rewrite)

The resonance cascade will turn reality into crystals that devours and destroy everything.
It can be triggered by delaminating the SM when is in contact with hypernoblium and antinoblium, both at over 40% and with as many moles to trigger a singulo delamination. The cascade can't be triggered if the SM is already under 80% integrity and if at any point any of the gases gets under 40% or the total gets lower than the amount for singulo, it will stop the cascade and can't be retriggered unless you reset the SM to over 80% integrity.
