Some savings due to, e.g., `area:iter`, and some unnecessary code removal / code simplifications
Some additional logging for getting more precise timings.
Not very spectacular, but also not invasive. The slow parts seem to be data transfer to/from the voxelmanip, lighting/water updates and the ore generation in nether, so not much in lua code.

this is a somewhat ugly hack that uses minetest.generate_decorations
which generates decorations regardless of biome so additional steps
had to be taken to ensure no other decorations "spill over" due to
this.
