Squirming Silverfish

Ever wanted silverfish to be easier, but not too easy, to spot? 

Then try out this pack! The infested blocks look almost the same, but they have a subtle (or not so subtle) give away - the squirming mass of a silverfish that lay beneath your pickaxe. 

I may release another version, depending on feedback, or if more infested blocks get added in future updates. Otherwise, this is feature complete. 

1.12.2 support coming soon. (completely different names for infested blocks)
