Invalid escape sequence in RegEx pattern

version_str = re.search("([0-9]\.*)*[0-9]", version_str).group(0)

/home/runner/.cache/uv/archive-v0/gQVN497zrc49u5GmIxX_f/lib/python3.14/site-packages/circuitpython_build_tools/build.py:46: SyntaxWarning: "." is an invalid escape sequence. Such sequences will not work in the future. Did you mean "\\."? A raw string is also an option.

I think the solution is to make it a raw string:

-    version_str = re.search("([0-9]\.*)*[0-9]", version_str).group(0)
+    version_str = re.search(r"([0-9]\.*)*[0-9]", version_str).group(0)

Otherwise, the escape char has to be escaped as well (\\.).

PS - Would it hurt to upload a bdist wheel to PyPI? I only got this warning because uv had to build this package from the source dist on PyPI (there are no bdist wheels available on PyPI).

Both changes would be welcome!

@tannewt If you would like to enable trusted publisher in the pypi project settings, then I can migrate to that in the process of introducing deployment of bdist wheels.
