Downloading maps of all regions of Norway doesn't download Oslo about osmand

[scaidermern]

Expected result

The map of Oslo should also have been downloaded.

Why?

The map for region Viken already contains Oslo. If you download the map for Oslo while having the map for Viken downloaded you will have duplicated data, leading to various problems (#15039).

The bug has been reproduced. To reproduce it, attempt to download all regions of Norway simultaneously. Once the download completes, you should observe that the Oslo map is missing.

Then I'm mistaken and Viken doesn't contain Oslo. This isn't obvious since when tapping on the Viken region on the map, OsmAnd displays it in such a way that Oslo is covered.

Probably bug is in Android, though if it's hard to fix we could extend map to contain Oslo similar to Brandenburg @Chumva @xmd5a2

[Chumva]

We filter some regions here by excluding nested subregions, avoiding duplication of what's already included in the top-level region

If we actualize Norway subdivisions then issue will be fixed automatically. Oslo was inside Viken region which was short-lived: https://en.wikipedia.org/wiki/Viken_(county)
Now there are 3 regions at Viken territory and Oslo. None of them contains Oslo inside it.

Yes we should follow new structure - 1 Viken
