Support for specifying a dependency via an import within the function itself instead of being passed in as a string in the decorator

[elviskahoro]

Pare example:

@pare.endpoint(name="3rd-party-deps", dependencies=["pydantic", ...])
def function_with_pyndantic_dependency() -> str:

I've used a similar service that's supports offloading a function / computation to the cloud. They supported including an actual import statement in the function itself in lieu of passing in a list of strings to dependencies. This developer experience was great and would be much appreciated!

@pare.endpoint(name="3rd-party-deps")
def function_with_pyndantic_dependency() -> str:

    import pydantic
    
    # use pydantic for something
    return "continue with function logic"
