Support tiled image servers

[JosiahParry]

Is your feature request related to a problem? Please describe.

User at the EPA wants to work with USA Noise pollution data. arc_raster() does not work with this because it is a tiled image service which does not have the exportImage endpoint.

Instead we need to use the tile/x/i/j format.

Here is the layer in question:

https://tiledimageservices.arcgis.com/P3ePLMYs2RVChkJx/arcgis/rest/services/USA_Transportation_Noise___Rail_Road_and_Aviation_2020/ImageServer

• sample layer from the docs https://sampleserver6.arcgisonline.com/arcgis/rest/services/Toronto/ImageServer/tile/13/2990/2289
