add benchmark for real wrapper classes around a JsonBuffer (#151)
This helps us to evaluate how much extension types are actually buying us, by benchmarking against thin wrappers around maps.
There are many advantages of real wrappers, such as type checks can actually work, and we can have many different implementations.
I have a specific idea in mind here, which is that the analyzer/CFE could provide their own thin wrapper implementations of these types, which wrap the analyzer/CFE representations and implement lazy getters. This would potentially allow us to handle all the query filtering, by just lazily reading the properties we care about into a new (buffer based) representation of the object, based on the fields present in the query.
Results are as follows:
