Digger - machine for gathering materials (ores, gems etc.) in a 5-block radius (X and Z position) beneath its Y level (down to 0). It requires an external inventory (like a chest) next to it. It uses 200 F per block (this can be changed at
diggerEnergyUsage field in Flux configuration file).
Digger will skip any block that is added in
flux:digger_skip block tag.
