Add exporter for table viewer

[Carifio24]

This PR adds an exporter for the table viewer. This implementation uses Plotly's Table trace. The basic approach is simple - we use the table viewer model to get the relevant data and colors, which are used to create the Plotly table's cells.

At least to me, there are two main features of the table viewer - manipulating layers, and sorting the table by a column. We can create buttons in Plotly to allow us to change the cells of the exported trace, but the relevant updated cells have to be pre-computed (that is, when we do the export). Thus trying to capture every possible state would create an extremely bloated export. This PR makes the choice to allow sorting, but not hiding/showing different layers, in the exported trace. Since each sort column requires another (sorted) copy of the data, this implementation presents users with a dialog to select which columns, if any, they want sorted. Sorting in the exported trace is done via a dropdown. If the user doesn't select any, the dropdown doesn't appear.

Since there's no legend (as there's only one trace), I've also added colored annotations that display the name of each layer. Also, the Plotly table has one feature that we don't, the ability to drag-and-drop to reorder columns, so that's a plus.

It looks like the CI errors here (and on main) are due to the bug that was fixed in glue-viz/glue#2377.
