implement original KINSHIP mechanics (economical change)

Author: yanik#0015 GotchiId: #4751 Discourse Thread: https://dao.aavegotchi.com/t/kinship-og-kinship-economical-proposal/4524

tl;dr

I propose to charge -4 kinship each time gotchi is channelling the altar.

This change gives a gotchi a choice to: (1) accumulate kinship (+2 kinship /day) and improve the character farming specs (2) take alchemica now and lose on the yield multiplier

By implementing this elegant and relatively simple solution, we are not only changing the alchemica dynamics and cutting the efficient inflation by 50% (in the wild should be closer to 60/40 or 40/60, depending on market conditions), but also making a game more strategic and exciting for long term players.

Such change is an excellent alternative to the current economic proposals and additionally will reduce the MATIC spend for channelling in half.

Cheers!
