Building the latest packaged pypi source distribution (0.1.5) doesn't work because Readme.md is not included

[aleloi]

Steps to reproduce:

run uv pip install --reinstall --no-binary :all: linetimer==0.1.5

expected results: package builds
actual results:

Resolved 1 package in 13ms
  × Failed to build `linetimer==0.1.5`
  ├─▶ The build backend returned an error
  ╰─▶ Call to `setuptools.build_meta:__legacy__.build_wheel` failed (exit status: 1)

      hint: This usually indicates a problem with the package or the build environment.

This is because the build step in setup.py tries to open the Readme, but the packaged source distribution on Pypi linetimer-0.1.5.tar.gz doesn't include it
