Subject: [PATCH] Say when a structure layer needs more zoom

Dense layers (Nether fossils every 2 chunks, mineshafts in every chunk)
are only drawn past a zoom level, and until now they stayed blank without
a word. Their row now reads "zoom in (150%+)" with the zoom they need.
Version 0.5.2.

+A clearer map for dense layers.
+
+## What's fixed
+
+- **Layers that are too dense for the current zoom now say so.** Some
+  structures are attempted very close together (Nether fossils every 2
+  chunks, mineshafts in every chunk), so the map only draws them when
+  zoomed in far enough. Until now such a layer stayed blank without any
+  explanation; its row now reads "zoom in (150%+)", with the zoom it needs.
+- Nether fossils only generate in soul sand valleys, so that is where they
+  show up once zoomed in.
+
+Matches Minecraft: Java Edition 26.3.
