[nodebinding] missing FromOject alternative

[davidkhala]

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.
