Shiny Widgets Integration

shinywidgets facilitates the rendering and interactive use of `ipywidgets` within `Shiny for Python` applications. It bridges the gap between the rich interactive capabilities of `ipywidgets` and the reactive framework of Shiny, allowing users to embed existing widget ecosystems like `ipyleaflet`, `plotly.graph_objects.FigureWidget`, and `ipyvolume` directly into their Shiny apps. The current version is 0.8.0, with a fairly active release cadence, often addressing compatibility with new versions of `ipywidgets`, `plotly`, and `websockets`.
