Entities

Entities are currently a complete mess since !15 (merged). There are several problems:

• Some entities (pandas I think) have hitboxes that are not horizontally squared (lbh, not bbh)
• The sizes changed between the versions
• The entity meta data is documented pretty bad in wiki.vg. We could use the burger format to analyze it in the snapshots.
• Rendering (!8 (closed)), this will be hard
• Entity Events (aka status). They are hardcoded and might change. ToDo
