The squid ink sac mob drop has been registered as `"mcl_dye:black"`
because it doubled as the black dye for lack of a proper black dye.
This commit makes the squid ink sac its own `"mcl_mobitems:ink_sac"`
item and updates the ink sac users (but not the black dye users.)
* Add craftitem for "mcl_mobitems:ink_sac".
* Update squid drop.
* Update crafting recipe for book and quill.
* Update fishing loot.
