[Enhancement] Reading Item Attributes from NBT Tags instead of just Lore

[luoxiawuchen]

Is your feature request related to a problem? Please describe.
Currently, the class attribute of the PSK plugin is implemented through LORE text recognition.

Provide a better way to read properties, similar to the mmoitems plugin, which generally allows applications to read attribute values by writing to nbt nodes.

Thank you for your patience in reading.
