Describe the bug
Custom-Model-Data gets lost with minecraft item type: "bundle"

To Reproduce
Steps to reproduce the behavior:

1. Save a bundle to json.
2. Give a bundle from json.

When saving:
[skJson] [STDOUT] SOURCE: ItemStack{BUNDLE x 1, BUNDLE_META:{meta-type=BUNDLE, display-name={"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"white","text":"Paket"}],"text":""}, lore=[{"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"gray","text":"An: "},{"bold":false,"italic":true,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"gray","text":"Kalabweg 1, Daria"}],"text":""}], custom-model-data=1, items=[ItemStack{SPRUCE_WOOD x 64}]}}

When giving:
[10:10:34 INFO]: [skJson] [STDOUT] SOURCE: ItemStack{BUNDLE x 1, BUNDLE_META:{meta-type=BUNDLE, display-name={"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"white","text":"Paket"}],"text":""}, lore=[{"extra":[{"bold":false,"italic":false,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"gray","text":"An: "},{"bold":false,"italic":true,"underlined":false,"strikethrough":false,"obfuscated":false,"color":"gray","text":"Kalabweg 1, Daria"}],"text":""}], items=[ItemStack{SPRUCE_WOOD x 64}]}}
