Replace pkg_resources to importlib.resources

[oatsu-gh]

Fix #135

• Replaced the deprecated package pkg_resources to importlib.resources, in order to use nnmnkwii even after 2025-11-30 with the latest setuptools>=81.
  • THIS CHANGE MAKE nnmnkwii INCOMPATIBLE WITH Python<=3.8, because importlib.resources.files is available only in Python>=3.9.
• Fix typo assertRaisesRegexp -> assertRaisesRegex
• Tested on Python 3.12.

Thank you! Can you update github actions settings to drop python 3.9 and add 3.12 instead?

[oatsu-gh]

Thank you for checking! Sure, I'll try that.

[r9y9]

looks like lint is failing. can you fix it? I'll triger CI again later

[oatsu-gh]

OK, checking now

[oatsu-gh]

Fixed import sort, to fix the isort linting error.

https://github.com/r9y9/nnmnkwii/actions/runs/17978488176/job/51140647384?pr=136 looks like CI still complains about linting issues

On python312, importlib.metadata.EntryPoints does not have method get, called from flake8.
On python311, it had.

This pysen's error is expected to be come from the flake8 incompatibility. I have no good ideas for now.

Newer pysen and flake8>=6.1.0 might solve these problems.
