Encoding Issue: unsupported type structpb.isValue_Kind

[pquerna]

Hello!

We have a bunch of Protobuf-based objects, which we use code generation to generate the ItemMarshaler and ItemUnmarshaler functions.

Since the new encoder went in #224 -- it looks like all struct fields are recursively scanned for support, even if the top level struct implements the Marshaler and Unmarshaler functions.

This leads to an error like this when we try to use dynamo:

dynamo marshal: unsupported type structpb.isValue_Kind

This is a nested field under one of our objects [our object as a Field of -> struct.Struct -> struct.Value]
https://pkg.go.dev/google.golang.org/protobuf/types/known/structpb#Value

Is it possible, if the top level object passed in implements the Marhsler interface, to not recursively scan the type?

Sorry about that. I'll try and get a fix out this weekend.

Just released v1.22.2 which should fix this. Please try it out.
