Loot cyphers, scroll tweaks, and more

[Robotgiggle]

• Adds ancient cyphers, which can be found in a variety of loot tables and come preloaded with a random hex
  • Ancient cyphers look like normal cyphers but with tarnished copper and slightly faded amethyst, and work identically
  • Unlike normal cyphers, they display their stored hex in the tooltip, so they can serve as a tutorial for new players
  • You can also erase them and put in your own spells using Craft Cypher
• Adds various new things related to Ancient Scrolls
  • You can now set the op_id without setting the pattern, which creates a scroll that loads your world's version of the pattern when ticked
  • There's now a creative mode tab containing all of the (base hex) scrolls, using the above feature to load the correct pattern when you grab one and put it in your inventory
  • The wandering trader now has a chance to sell one random scroll for 12 emeralds, which only reveals its stroke order when you buy it (finally, a way to get scrolls in skyblock!)
• Adds two custom loot tables (hexcasting:random_scroll and hexcasting:random_cypher) that produce a guaranteed scroll or ancient cypher when generated
  • These aren't used anywhere in game, they're intended for use by packmakers or addon devs
• Assorted new config options
  • Injection list and injection chance for ancient cyphers, just like how it works for lore fragments
  • List of preset hexes for ancient cyphers
  • Chance for wandering trader to sell a scroll
  • Toggle to enable comma-separated pattern lists
