Test app on other datasets

E.g. global.health.

Potentially also relevant to test datasets (godataR etc.) in other workstream.

The demo by @sbfnk is a really helpful and clear resource to guide dataowners or users with other datasets through the analysis and setup.

The only suggestion I have is to include examples of another dataset from outside the epishiny data pools already tested https://github.com/epiverse-trace/epishiny/blob/vignette/vignettes/external_data.md showing sample outputs that the users should expect. This can also serve as a dogfooding excercise!
