Timechart

What's Changed

This is a packaging maintenance update release for PyPI.

**NOTE**: Version v1.5.0 has been yanked from PyPI.

This is due to the mistaken inclusion of vendored `pydm` and `pyqtgraph` libraries. It appears this may have been due to a broken environment when the source distribution archive was created. If you have a tag relying on v1.5.0, please update it to `>=v1.5.1`.
