Would adding py.typed suffice to add mypy support ?

[JonathanPlasse]

Hi,
Love pymap3d.

When running my code with mypy without --ignore-missing-imports, I get the error Skipping analyzing "pymap3d": module is installed, but missing library stubs or py.typed marker.
Would adding py.typed suffice to add mypy support as described here?

Never mind, it would cause problems as the current typing would cause problems.
Returning tuple instead of tuple[float, float, float] for example.

Is there a way that doesn't cause problems when the same function can return either tuple[float, float, float] or tuple[numpy.ndarray, numpy.ndarray, numpy.ndarray]

[JonathanPlasse]

Here is a solution

try:
    from numpy.typing import NDArray
except ImportError:
    pass

@overload
def enu2aer(e: float, n: float, u: float, deg: bool = True) -> Tuple[float, float, float]:
    pass


@overload
def enu2aer(
    e: "NDArray", n: "NDArray", u: "NDArray", deg: bool = True
) -> Tuple["NDArray", "NDArray", "NDArray"]:
    pass

If numpy is installed, vscode hints would show,

enu2aer(e: float, n: float, u: float, deg: bool = True) -> Tuple[float, float, float]

enu2aer(e: NDArray, n: NDArray, u: NDArray, deg: bool = True) -> Tuple[NDArray, NDArray, NDArray]

Otherwise,

enu2aer(e: float, n: float, u: float, deg: bool = True) -> Tuple[float, float, float]

enu2aer(e: Any, n: Any, u: Any, deg: bool = True) -> Tuple[Any, Any, Any]

I am working on a PR to apply this to the rest of the code
