[nodebinding] missing FromOject alternative

**I want** a way to transform a javascript object(or json) to a protobuf binary without set attribute mannually to align schema.
We have found a simple way to do so when using `fabric-protos`, which depended on protobufjs
```
typeObject.encode(JSObject).finish()
```
where the typeObject is the type constructor or type itself such as gateway.EvaluateRequest

Now I wonder if we can have similar clean solution now in `@hyperledger/fabric-protos`.
