seqrepo cli not installed in 0.6.6 and 0.6.7

[reece]

Describe the bug

Some change between 0.6.5 and 0.6.6 causes the seqrepo command line script to not be installed. This issue affects local (dev) installation and the pypi packages. 0.6.7 has the same issue.

To Reproduce
Steps to reproduce the behavior:

1. Create a venv
2. pip uninstall biocommons.seqrepo, pip install biocommons.seqrepo==0.6.7, then seqrepo. You should see seqrepo: command not found.
3. Try again with 0.6.6. Same outcome.
4. Try again with 0.6.5. seqrepo should start and show the help message.
5. The same occurs in a development environment with something like git checkout 0.6.7; pip uninstall biocommons.seqrepo; pip install -e .[dev].

Expected behavior

The seqrepo command line tool should be installed in all versions.

I have been unable to isolate the underlying cause, but switching from setup.cfg to pyproject.toml seems likely.

Note that biocommons.example works as expected.

Just on my phone between baby naps, but the blame definitely points my way. Maybe setuptools is unhappy when entry_points is still defined in setup.py/cfg but other parts of the build specs have been moved to pyproject.toml? Either way, an overwrite of my last PR with the stuff in the example template is overdue, so if that also fixes this issue, then that's two birds at once

Found it. The error was my merge at ee80d92. I'll fix.

@larrybabb I think this is the issue you were encountering today.
