Directional Ore Detector
It should be possible to scan for ores also directionally in cone, not just in globe.
I think the best thing would be to add new 'cone width' to Ore Detector.
If set to 360, it will function like current version. Max scan length should change according to volume scanned, thus narrow cones could scan much further.
Every layer of voxel should decrease effective scan range - thus it would be harder to detect deep ore on planets than exposed ore on far-away asteroid.
Also, if both cone width and scan depth are to be configurable, the detector should use proportional amount of power.
