📊 mpox: get data from the WHO Shiny App

[spoonerf]

Hey @Marigold - it looks like the data for suspected cases is base64 encoded in the WHO Shiny App. I've had a go at extracting it here, but not sure how solid the snapshot method is.

This could be a new source of suspected cases and deaths from the WHO, but annoyingly they don't include data for either of these prior to 2024, when I think there were suspected cases from Sept 2023.
