Add a path layer to the deckgl widget

The PathLayer takes in lists of coordinate points and renders them as extruded lines with mitering.

add_path_layer(
  deckgl,
  data = NULL,
  properties = list(),
  ...,
  id = "path-layer"
)

Arguments

deckgl: A deckgl widget object.
data: The url to fetch data from or a data object.
properties: A named list of properties with names corresponding to the properties defined in the deckgl-api-reference for the given layer class. The properties parameter can also be an empty list. In this case all props must be passed as named arguments.
...: Named arguments that will be added to the properties object. Identical parameters are overwritten.
id: The unique id of the layer.

sample_data <- paste0(
