Mashumaro is faster and doesn't come with all versioning problems that
pydantic does.
A basic perf test deserializing all of our discovery results fixtures
shows mashumaro as being about 6 times faster deserializing dicts than
pydantic. It's much faster parsing from a json string but that's likely
because it uses orjson under the hood although that's not really our use
case at the moment.
