[SBM] Heavy Lamp

The [SBM] Heavy Lamp modification introduces a unique block - the heavy lantern, which obeys the laws of gravity. This paper lantern falls down if there's no support beneath it, making it an extremely useful tool for mines and quarries.

The primary use of the heavy lantern is to simplify the resource extraction process, especially during nighttime. Instead of constantly placing torches on mine walls, you can set up this lantern in a quarry and dig underneath it safely. As you go deeper, the lantern will descend with you, providing continuous illumination of the work area.

In addition to its practical mining applications, the heavy lantern can serve as an interesting decorative element, adding atmosphere to your builds.
