UE5.4 support, struct names, binrw

[scottanderson]

• Complete rewrite of model structs using binrw, with ~90% of types completely derived.
• Struct names are based on the corresponding Unreal Engine types.
• Support for Palworld save files through dedicated wrapper types.
• Fixes Palworld test are slow #56
• Fixes Unable to read save file for Medieval Dynasty #103
• Fixes Improve the separation of Property tags from property values #114
• Fixes [UE5.4] Property tag serialization support #134
• Bump package version to 0.11.0

Incomplete

• Type hints are not implemented. When type information is unavailable, FStructProperty::Custom will attempt to parse the property, and in the event that parsing fails, FStructProperty::Unknown will be used as a generic fallback. This type is distinct from FProperty::Unknown, because a UE4.5 FStructProperty::Unknown has its own type metadata and struct-guid.
