Overzoom for satellite images

I think this is the issue I'm having with satellite view; when I zoom too much (in Croatia) in I get fake tiles with "Map data not yet available" instead.

e.g. tiles like this:
https://server.arcgisonline.com/arcgis/rest/services/World_Imagery/MapServer/tile/19/192042/286914

The solution might be as easy as adding ?blankTile=false to the end of that arcgisonline URL (See e.g. Helium314/SCEE#724)

e.g.
https://server.arcgisonline.com/arcgis/rest/services/World_Imagery/MapServer/tile/19/192042/286914?blankTile=false
(that will return 404 error instead of fake tile, which is usually detected and used to support overzoom)

Unfortunately, everything is more complicated due to Leaflet and script features. Simple addition ?blankTile=false doesn't work, because Leaflet will just show an empty tile. I can't just limit the maxZoom, because it's different in different places on the planet. + ESRI is not a new layer, but a dirty hack with replacing the src of OSMF tiles.

I'm still experimenting with maxNativeZoom and disabling 404 tile handlers, but so far it's all very unstable. In the good news, in the new version of script, the satellite layer will work in Chrome.
