Archotech Stack Gene

Some anonimos adventurers successfully stole the fully working gene blueprint of the cortical stack right from the nose of the Archotech. It's not craftable, but you can grow one with this brand new gene, and it uses vanilla biotech resourse - archite capsules.
Wanna make a specific pawn last longer than one fight with a giant ancient spider? Simply slap this gene on, and you're done. Don't be afraid of losing stack; if you change the xenotype of the carrier, it will only kill a sleeve (and stack drops nearby). Archotechnic stacks are undestructable. You can use this mod as some kind of biotech endgame, or you name it!
Lore-wise, every carrier of this gene was a pet of Archotech for a while and got it as a reward for loyalty. But you can find them in a trader's gene packs if you want; the possibilities are endless! Thanks to Helixien for Altered Carbon mod, and Vanilla Expanded team, that framework really makes my silly ideas possible

Tested:
1)adding this gene to a blank sleeve before growing it gonna end up with botched sleeve and broken stack, that is contains soul of a mindless husk. I advice you not recreate this particular scenario.
2) After using "Skipstack" ability carriers of this gene gonna loose their stack, and drop dead, but stack going to continue to exist so you not lose your colonist, jist a body that caries the gene
To do:
10 archite capsules gonna cost you around 7000 silver, empty archostack is worth 3000. I gonna adjust the archite capsules price after some testing.
