## In-Memory Mapping Benchmarks
Tests the following approaches:
1. Dynamic: creating object (hierarchies) by direct assignment of values from
a `dynamic` (anonymous) object using C# DLR dispatch
2. AutoMapper: using the same in-memory (anonymous) object and mapping to a
typed model.
3. MessagePack: deserializing from a memory stream (same object structure, but
from annotated object model)
4. System.Text.Json: deserializing from a memory stream populated by serializing
the (anonymous) object using Json.
