Pydantic datatype validation for hamilton nodes

[elijahbenizzy]

Is your feature request related to a problem? Please describe.
We have pandera, we should have pydantic as well.

Describe the solution you'd like

class MyModel(BaseModel):
    ...
# mode 1
@check_output(schema=MyModel)
def foo() -> dict:
    ...

# mode 2
@h_pydantic.check_output_schema()
def foo() -> MyModel:
    ...

Describe alternatives you've considered

I, personally, find pydantic to be overkill for most cases and think the world should have united around dataclasses/typed dicts, separate from validation. That said, everyone uses it, so 🤷 .

Task:

• add some data validators that work like the pandera schema= one but for pydantic

@elijahbenizzy and @skrawcz - is this issue currently being worked on? If not, do you mind if I take a crack at it? Thanks!

@cswartzvi go for it! You should be able to mirror the Pandera implementations I think. And if there's something structurally that could be better, let us know :)
