Add tests for numba and with typeguard

[gatoniel]

This issue agronholm/typeguard#277 is solved now. Test and incorporate.

This is currently still not working as typeguard is not yet released on pypi and nox_poetry has some issues with installing from github...

However, it is unclear whether version 3.0.0rc1 seems to solve the issue. Using the file test.py with

from typing import TypeVar

import numpy as np
import numpy.typing as npt
from numba import njit
from typeguard import typechecked

T = TypeVar("T", bound=np.generic)


@typechecked
@njit
def numba_sum(
    array: npt.NDArray[T],
) -> T:
    return np.sum(array)


x = np.arange(4)
s = numba_sum.py_func(x)
s = numba_sum(x)

and running the command poetry run python test.py gives the warning

/home/niklas/.cache/pypoetry/virtualenvs/merge-stardist-masks-Mk5qjuGF-py3.9/lib/python3.9/site-packages/typeguard/_decorators.py:170: InstrumentationWarning: Cannot instrument __main__.numba_sum -- @typechecked only supports instrumenting functions wrapped with @classmethod, @staticmethod or @property
  warn(

Using nox -s typeguard -p 3.9 gives several errors.
