Alshanex's Familiars

This update aims to fix the compatibility issues with latest version for Iron Spells and Spellbooks.

This version fixes all the issues with ISS v.3.15.0, which also implies that this won't work with previous verisons of ISS.

As an addition to thank all the people that supported the 1.20.1 version of the mod even in the discontinued state, i've backported the entire structures update, so enjoy exploring new structures and of course, Origin Island is here, which also means that rituals are now avaliable in this version!

Report any bugs with this version on the github, i'll fix any bugs with this version but i won't backport any more stuff (since the remaining stuff heavily relies on Neoforge 1.21.1 specific stuff)

Anyways, thanks for all your support and have fun! :)
