Torturable Healthbars, but with FA

Many changes, i'll just copy the update section over here

2.1 Let's celebrate 1.21 with 2.1 of TH, with many changes, toggleable stuff, cool reworks, bug fixes and a new sibling to the Healthbars "family": Compatible Healthbars, in alpha, just go look at it it's cool. The wither has been remade (look at the gallery), the ghast has been remade, the snow golem no longer glitches, we have the bogged and the breeze, more animated blood and armors can now crack, with these last 2 additions being toggleable with Respackopts

Other than that, many bug fixes for THFA, including some weird shulker and silverfish things
