Bump version to 5.2

I don't think there were any API changes, but a change was made for Python 3.13.  I think a
minor version upgrade is warranted.

Release 5.1.0

Release 5.0.1

Fixes to allow build artifacts

- Removed a delegating ctor which fails on macOS gcc with error "delegating constructors are
  permitted only in C++11".

- Add version to toml file, required by cibuildwheel (and pyproject.toml specification, I
  think) and have setup.py file extract it dynamically so we only have to maintain one.  I need
  to determine if the setup keywords are even required or if it will pick up items from the
  toml file.

Cleaned up setup.py and marked as 5.0.0a1
