Port the v3 map as iris std map

- iris std map opens the v3 map window; noise, palettes, objects, procedural and image maps are views in it
- Rivers view draws v4 hydrology, with an empty state when the pack has rivers off
- 3D views fall back to software when LWJGL isn't on the classpath; modded jars use the game's LWJGL
- FlatLaf and LWJGL join core; v4's separate studio windows are removed
