Decoding grpc-status-details-bin ?

Hi there

Server side, we send an error withDetails (in GO) :
```
st2 := status.New(codes.Aborted, "failed to map")
st2.WithDetails(&Error{
Code: 1,
Message: "error",
})
```

Client side (js / typescript), we need to retrieve these details somehow but all we receive is a serialized string (`trailers.get('grpc-status-details-bin')` ) .. how can we decode it ?

Thanks
