More innerSeams, less confusion

- Add `innerSeams` support to all applicable methods (`horizontal`, `vertical`, `h+v`, `v+h`, `top`)
- Rewrite connection map calculation for some processors to be more efficient and compact
- Change BlockState retrieval across all processors to be more efficient and make more sense
- Change seeding method for `random`
- Move check for one sprite from RandomSpriteProvider to Factory
- Remove StandardOverlayQuadProcessor.BlockStateAndBoolean
- Do not normalize normal vector if its length is zero in CompactCTMQuadProcessor
- Move OptionalListCreator into CTMPropertiesLoader
- Standardize locations of Override and Nullable annotations
- Require Fabric API >=0.58.0
