 Utility function for deserializing the `grpc-status-details-bin` metadata value when using the [grpc-js](https://github.com/grpc/grpc-node) package. Error details allow sending/receiving additional data along with an error. For instance, if a request sends invalid data, a gRPC server could send back a [BadRequest](./src/proto/error_details.proto#L119) message identifying the field and why it failed validation.
