Map ipaddress.IPv4Address, IPv6Address, IPv4Interface, and IPv6Interface to their corresponding marshmallow field classes in Schema.TYPE_MAPPING, enabling automatic field resolution for libraries like marshmallow_dataclass.

There was a problem hiding this comment.
This test feels gratuitous because it's just testing the implementation. i'll remove for now

Summary
Closes #1695.
Adds mappings from Python's
ipaddresstypes to their corresponding marshmallow field classes inSchema.TYPE_MAPPING:ipaddress.IPv4Addressfields.IPv4ipaddress.IPv6Addressfields.IPv6ipaddress.IPv4Interfacefields.IPv4Interfaceipaddress.IPv6Interfacefields.IPv6InterfaceThis enables libraries like
marshmallow_dataclassto automatically resolve these types from annotations.Note: The generic
IPandIPInterfacefields are intentionally excluded since there is no single Python type that maps to them.IPv4Network/IPv6Networkare also excluded since marshmallow does not have corresponding network field classes.Test plan
