Minor Changes

• feat: Add support for evented msgspec.Struct objects (#64)

  Our experimental descriptor API can now work with msgspec, a fast and efficient serialization library, similar to pydantic but with a stronger emphasis on ser/de, and less on runtime casting of Python types.

  from anywidget._descriptor import MimeBundleDescriptor
  import psygnal
  import msgspec
  
  @psygnal.evented
  class Counter(msgspec.Struct, weakref=True):
      value: int = 0
      _repr_mimebundle_: ClassVar = MimeBundleDescriptor(_esm="index.js", autodetect_observer=False)
