What's New:

User Changes:

This update extends the expression syntax to support nbt and block properties.

• Returned to downloading mappings at startup.
• Compound and List NBT tags are now properly supported.
• Added nbt field to item stacks, entities and block entities.

This Allows you to access NBT data like so: this_entity.nbt.Air. You should avoid NBT access, as it can get extremely slow.

• Added properties field to *states.

This can be used to access block state properties like so: block_state.properties.candles.

• Added lots of new functions. Consult the wiki for more info!
• Added short_circuit to defaulted, all_of, any_of. If true, commands will terminate immediately upon the condition failing.
• hasContext and structContainsKey now accept VarArgs.
• Removed arbitrary map support, as it was pretty poorly implemented.
• Constants are now case-sensitive.

Dev Changes:

• Moved Command codecs to MapCodec.
• Added BooleanExpression, similar to Arithmtica.
• Added runTriState to EventExecutors.
