Fixes #480

[mhostetter]

@Minnerlas can you install the .whl file inside this zip (built from this branch) and see if it provides the correct flags to mypy. And if the types in galois play well with mypy? I really have never tested with mypy. Thanks.

I verified this is packaged correctly and works with mypy.

# file: test.py
import galois
GF = galois.GF(256.0)

Before

PS C:\Users\matth> python3 -m mypy test.py
test.py:1: error: Skipping analyzing "galois": module is installed, but missing library stubs or py.typed marker  [import]
test.py:1: note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports
Found 1 error in 1 file (checked 1 source file)

After

PS C:\Users\matth> python3 -m mypy test.py
test.py:3: error: No overload variant of "GF" matches argument type "float"  [call-overload]
test.py:3: note: Possible overload variants:
test.py:3: note:     def GF(order: int, *, irreducible_poly: Optional[PolyLike] = ..., primitive_element: Union[int, PolyLike, None] = ..., verify: bool = ..., compile: Optional[Literal['auto', 'jit-lookup', 'jit-calculate', 'python-calculate']] = ..., repr: Optional[Literal['int', 'poly', 'power']] = ...) -> Type[FieldArray]

I am sorry, I haven't seen that I was tagged until now. Thanks for the quick fix though!

[mhostetter]

No problem. Open another issue if v0.3.5 has issues with mypy.
