Vignette on OSM-based networks

[luukvdmeer]

I think it is nice to have a dedicated vignette on OpenStreetMap-based networks. This vignette would present a full workflow starting with obtaining OSM data (show example both with osmdata and osmextract), preparing the data for network construction (e.g. duplicating linestrings that can be travelled in both directions), constructing a network, cleaning the network (e.g. running to_spatial_subdivision) and finally analyzing the network (e.g. calculating shortest paths). This vignette would in some way be an updated version of our r-spatial blogpost from September 2019, although there is not requirement it should have exactly the same content.

@loreabad6 has volunteered to work on this, possibly needing input/feedback from @agila5 and @Robinlovelace along the way
