Add support for DeepFriedMarshmallow

[illusional]

DeepFriedMarshmallow is a drop-in JIT for Marshmallow, but some nested objects don't handle the deepcopy well. We can preempt this by subverting the deepcopy with a shallow copy (through reinstantiation).

It supports marshmallow = ">=3.13.0,<5.0.0"

Ah, because marshmallow fields are sorted in marshmallow 4, the list comparison fails.
