Support "ggnewscale" through geom_NewGeomLine etc

There are many use cases where a user wants to split a colour (or any other attribute) scale into multiple components. For example, if two separate types of data are being presented and it doesn't make sense to compare colours between these datasets.

In the example below, I am visualising a time series with time/y coordinates using geom_line, and also known timepoints that have only time coordinates using geom_vline. Note that this renders correctly using ggplot, but results in a blank plot and many errors with ggplotly:

Ideally the entire package ggnewscale would be supported in ggplotly. Internally it seems to use functions such as geom_NewGeomLine, and these are the functions that plotly would need to implement to get this to work.

Comienza reproduciendo el ejemplo proporcionado de ggplotly y siguiendo las advertencias de geom2trace.default para geom_NewGeomLine. Revisa cómo ggplotly gestiona estos geoms generados, determina después la compatibilidad necesaria para el ejemplo de ggnewscale y verifica que se renderiza sin las advertencias indicadas.
