- gold_ores block & item tags: now contains deepslate_gold_ore

Custom Worlds:
- New ore_tuff
- Tuff ore blob added to all vanilla biomes

- Geode features now have an invalid_blocks_threshold field.
- More air blocks than that in the center of the geode causes it to not generate

- Ore features can now define the chance that an ore is skipped if it is exposed to air: discard_chance_on_air_exposure (float between 0 and 1)
- New ore_iron_middle (unused)

- Noise settings: grimstone_enabled renamed to deepslate_enabled

- Fields that used to be uniform floats now have a type and several available random distributions:
- constant value - either just a float or "constant" type and a value field
- uniform - works like before, base and spread data
- trapezoid - min, max and plateau fields
- clamped_normal - mean, deviation, min, max

- dripstone_cluster feature no longer has wetness_mean and wetness_deviation fields, uses a clamped_normal float value provider instead

- Carvers now have a debug_settings field, allowing you to switch on debug mode. In debug mode, all carving leaves a special block state as a trace
- Canyon carvers are now configurable:

- Two vertical anchors: bottom_inclusive and top_inclusive for defining height span
- horizontal_radius_factor - float provider that determines horizontal radius
- vertical_radius_default_factor and vertical_radius_center_factor - floats. the default factor adds radius regardless of where, the center factor adds radius depending on where in the height span you are
- thickness: float provider
- distance_factor: float provider
- width_smoothness: int, determines how smooth the sides end up being
- y_scale: int or a uniform int provider
