Block.from_palette() broken by Minecraft 26.3

[Densaugeo]

Not sure if this library is still maintained. Either way, I have a monkey patch that allows Block.from_palette() (and functions that call it like Chunk.get_block()) to work with Minecraft 26.3 .mca files:

import anvil, nbt

# Minecraft 26.3 added 3 new formats for storing a block's name. The old format
# still appears in blocks that haven't been loaded since the update, for a total
# of 4 possible formats
@classmethod
def anvil_Block_from_palette_override(cls,
tag: nbt.TAG_Compound | nbt.TAG_String):
    # After 26.3 section palettes in which all blocks are in default state now
    # use plain string tags instead of compound tags
    if type(tag) == nbt.nbt.TAG_String:
        return cls.from_name(tag.value)
    
    # After 26.3 block which are in default state but not in a plain string
    # section use "" inseat of "Name" and omit "Properties"
    if '' in tag:
        return cls.from_name(tag[''].value)
    
    # After 26.3 block which are not in default state use "id" instead of "Name"
    # and "properties" instead of "Properties"
    if 'id' in tag:
        return cls.from_name(tag['id'].value,
            properties=dict(tag.get('properties', dict())))
    
    # Pre-26.3 format
    if 'Name' in tag:
        return cls.from_name(tag['Name'].value,
            properties=dict(tag.get('Properties', dict())))
    
    raise NotImplementedError('Block format not recognized - did Minecraft add '
        'a new one?')

anvil.Block.from_palette = anvil_Block_from_palette_override

I haven't tested for backwards compatibility, but if this library is still maintained I could send a PR.
