Partly deserializing a JsonObject for a known property

Created by: smuellener

I would like to deserialize a JsonObject partly to save memory by not deserializing properties of unknown size.

Example:

I have a string containing a serialized partly known object:

{
    "UnknownProperty": "valueWithUnknownSize",
    "KnownProperty": "valueWithKnownSize"
}

Is it possible to only deserialize a known specific property from a serialized object?

E.g.:

StaticJsonDocument<64> doc;
deserializeJsonSpecificProperty(doc, example, "KnownProperty");

This would be helpful for a library that only knows (the required size for deserializing) part of the object. Thanks!
