Replace depracated Numpy dtypes

[pnuu]

With a new production chain I noticed the following depraction warning in the logs:

lib/python3.9/site-packages/pyresample/kd_tree.py:968: DeprecationWarning: `np.int` is a deprecated alias for the builtin `int`. To silence this warning, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
Deprecated in NumPy 1.20; for more details and guidance: https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations
  radius=self.radius_of_influence, dtype=np.int,

This PR replaces all the usages of np.int, np.float and np.bool with the preferred versions listed in the third column of the Release Notes for 1.20.0.

Do we just want to force this to int64 to ensure 64-bit precision?

I also think there is an np.float somewhere in kd_tree.py somewhere but when I switched it to float64 it started failing...I think.

Coverage increased (+0.006%) to 93.611% when pulling 015efc2 on pnuu:fix-deprecated-np-int into ee7c1b9 on pytroll:main.

[pnuu]

I changed them to np.int64 and np.float64 to be explicit. And swapped np.bool to np.bool_ to be consistent with the others.

Apparently pytest-lazy-fixture was missing from the test_requires as I couldn't run the tests locally. As the tests ran on CI, I assume it was explicitly installed there.

[pnuu]

The tests don't pass locally on Python 3.9, which doesn't seem to be use in the CI at all!

[pnuu]

Python 3.9 test runs added in #396

[djhoese]

Do you want these to be np.int64 too?

[pnuu]

Yeah. Thanks, missed them in the previous change 🤦‍♂️

[djhoese]

Small double check on one remaining int, otherwise LGTM
