Dynamically resample Esri World Imagery

[jwasilgeo]

Investigate the possibility of dynamically resampling (with the help of relying on service tilemaps) the Esri World Imagery raster basemap which has tiles available in some regions of the world beyond zoom level 19.

• Original issue Latest ArcGis jsapi library resamples images, this doesn't #240.

• PR dynamically resample Esri World Imagery #1011 (it resolved Latest ArcGis jsapi library resamples images, this doesn't #240 but we decided to revert on 27 July 2020 via PR revert-pr-1011 #1223; see discussion in issue The maxNativeZoom option of the layer is not being set when using L.esri.basemapLayer #1210).

• Subsequent bug issue The maxNativeZoom option of the layer is not being set when using L.esri.basemapLayer #1210 where we identified some behavior that needed extra attention to fix.

  Need to understand how to deal with the missing tiles behavior described in The maxNativeZoom option of the layer is not being set when using L.esri.basemapLayer #1210 (comment), The maxNativeZoom option of the layer is not being set when using L.esri.basemapLayer #1210 (comment), and The maxNativeZoom option of the layer is not being set when using L.esri.basemapLayer #1210 (comment).

• Take care not to attempt to apply these changes to other imagery-related basemaps (see related bug issue ERR_NAME_NOT_RESOLVED while zooming in with ImageryClarity #1197).

Perhaps also investigate if we could use the tilemap resampling approach among all other Esri raster tile basemaps since they do not cook tiles over the ocean beyond zoom level 13. See comments in PR #1223 (review).
