Changes

Switch to loadable for handling the JSON parsing for generator sprites

Nicer than JSON as I have control over default values. Took the opportunity to rename the fields to use snake case

Add support for animated textures to the material texture generator

The only thing that was really needed was mcmeta and the ability to disable animation on certain sprites, but since we want to use this also provided an implementation

Implement blazewood as a new shield core type

To make its trait work, slot in charge module now tracks the total modifier level, given this is not the first case that wants a slot in charge of total level (need it for any non-composable formulas)

Add armor materials to the book

Due to when you gain access to armor, and the fact that tier 1 is so weird, tier 1 is merged with tier 2 in puny melting
In the encyclopedia, all 4 tiers are in 1 section as we were starting to get too many sections. Ended up merging the melee/harvest and raged materials into single sections as well

As part of this commit, deleted the deprecated material section transformers from various books, no longer needed
In addition, cleaned up quite a bit of material page code, should make it a bit faster

Stop material pages from showing composites from casting on themselves

Couple of visual variants of iron and copper do this, its just confusing

Remove advancement unlocking of encyclopedia sections

With tool materials merge into a single section, only modifiers were left unlocking as tools were long since just always unlocked.
While it was a neat feature, it really did not add anything and its not worth keeping around for just modifiers.
