Ludovic Marie 139c5abd1c Port the DataFixers of 1.19 to 1.20 for worlds from 1.18.2 on 
The fixes from 3076 to 3459 (game event, cat, frog, painting, goat, goat
horn, filtered text, POI, blending, spawn egg, effect duration, archaeology,
double-sided signs, the 1.20 experiment and chunk statuses), the block
entities their schemas add, and block entities' remainders (a decorated
pot's shards stay next to its sherds). The sample world generator logs in
to 1.18.2 to 1.19.4 servers and gates the scene by version.

"""Scenes for tools/datafix_worlds.py: block entities, entities and items in the save
formats of older game versions, placed by console commands of that version.
Three syntax eras matter for the commands:
A before 1.20.5 (DataVersion < 3818): item `tag` NBT, `Count`, JSON text strings
B 1.20.5 to 1.21.4 (< 4325): item components, JSON text strings
C 1.21.5 and later: item components, SNBT text components, `equipment`
Every entry is (minimum DataVersion, command template). `{x} {y} {z}` are filled
with a free position; entities get a fixed UUID so outputs can be matched.
