pkg_resources removed in python 3.12

[2bndy5]

Using python 3.12 to build bundles results in the following error:

  File "/opt/hostedtoolcache/Python/3.12.0/x64/lib/python3.12/site-packages/circuitpython_build_tools/scripts/build_bundles.py", line 40, in <module>
    import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

setuptools has a migration guide (from pkg_resources to importlib.resources).

Possible replacements

circuitpython-build-tools/circuitpython_build_tools/scripts/build_bundles.py

Lines 271 to 272 in 9f02e3a

	if "TRAVIS" in os.environ:
	mpy_cross = pkg_resources.resource_filename(

could be replaced with the suggestion from the aforementioned migration guide.

Note

The above snippet seems to specifically support using Travis CI. Travis CI isn't used in CirPy CI workflows anymore, and they no longer have a free tier (maybe some customers were grandfathered into current pricing?).

And then there's this (seemingly antiquated) statement in the README:

These build tools are intended for use with Travis CI

---

circuitpython-build-tools/circuitpython_build_tools/scripts/build_bundles.py

Lines 247 to 250 in 9f02e3a

	pkg = pkg_resources.get_distribution("circuitpython-build-tools")
	build_tools_version = "devel"
	if pkg:
	build_tools_version = pkg.version

could be replaced with importlib_metadata.version()

TBC

I haven't delved into the impact of these changes, but I figure d I'd better open an issue to track this for future support of python 3.12.

can you put this in as a PR so that we can see what the CI thinks about the proposed change?

[2bndy5]

I can draft up something. But I can't test anything in Travis CI anymore.

[jepler]

we don't use travis anymore for anything circuitpython related

[2bndy5]

Should I remove that travis-specific code block? If so, I think the README should also be adjusted accordingly.

Correcting the README with current info would be good, but let's handle the pkg_resources problem separately from that.
