holoviz/holoviews: Version 1.16.0

This release includes many new features, improvements, and bug fixes. Among the highlights are support for Bokeh 3.1 and Panel 1.0, both of which come with a wide range of new features and enhancements. Time series support has also been improved, with auto-ranging along one axis, a new downsample algorithm, and having WebGL enabled by default. In addition, the release includes various other enhancements and bug fixes.

We would like to thank the many users who contributed to this release by filing bug reports, providing new features, and bug fixes. We want to give a special shout-out to existing contributors @ianthomas23, @jlstevens, @jordansamuels, @maximlt, @philippjfr, @TheoMathurin, @Yura52, and @Hoxbro, as well as new contributors @GeoVizNow, @JRRudy1, @keewis, @michaelaye, and @wendrul.

This minor version will be the last to support Python 3.7. The next minor version will require Python 3.8 or higher. In the next release, holoviews.annotate will start giving a deprecation warning about its future move to the new package HoloNote.
