[Bug]: TypeError: unhashable type: 'ImportFromModule' for User Defined Functions

[zcipod]

Describe the bug

I got this error when I created a user defined function:
TypeError: unhashable type: 'ImportFromModule'

Steps to reproduce

My function is like this:

@with_requirements(python_packages=["requests", "urllib3"], global_imports=["requests", "os", ImportFromModule("urllib.parse", ["urlencode"])])
def search_from_web(search_keyword: str):
    pass

The exception is caused by this function under func_with_reqs.py:

def _build_python_functions_file(
    funcs: List[Union[FunctionWithRequirements[Any, P], Callable[..., Any], FunctionWithRequirementsStr]]
) -> str:
    # First collect all global imports
    global_imports = set()
    for func in funcs:
        if isinstance(func, (FunctionWithRequirements, FunctionWithRequirementsStr)):
            global_imports.update(func.global_imports)

    content = "\n".join(map(_import_to_str, global_imports)) + "\n\n"

    for func in funcs:
        content += _to_code(func) + "\n\n"

    return content

The ImportFromModule is unhashable at global_imports.update(func.global_imports)
