- Update to version 1.18.0:
* update dependencies (require lalsuite, no longer require
emcee).
* build wheels and update build infrastructure.
- Drop usage of python singlespec macros and switch to supporting
just the default python3 environment. The large number of
binaries installed to _bindir and the lack of a reasonable way
to use python_clone for all the binaries forces this change.
- Promote lal* to Requires and drop BuildRequires/Recommends on
python-emcee in keeping with upstream changes.
- Drop additional source utils.py: not needed any more.
- Enable tests after deleting broken test cases.
- Add BuildRequires/Requires on lalpulsar, python-ligo-lw,
python-lscsoft-glue: new upstream dependencies.
- Switch source tarball to GitHub since PyPI tarball does not
carry the helper scripts and data files for test suite.
