New application of fireflies

Please add 2 items. Namely: an empty lamp and a lamp with fireflies. An empty lamp can be made in the same way as an ordinary lamp, but without a torch. To make a lamp with fireflies, you need to put an empty lamp in the mangrove swamp biome next to the fireflies, and after a while they will climb into the lamp. This would add a new application of fireflies and a new light source.
