Fire fly nests that stops hostile mob spawning in an area.

It seems like fireflies aren't gonna end up as mojang planned as their main purpose has been given to the magma cube so I've thought of an idea on how to implement them.

Firefly nests are similar to spore blossoms where if you place it anywhere, the firefly particles will follow. Firefly particles will indicate how far the nest's effect reach which will probably be 12/24 blocks far (similar/twice the reach of torches).

Firefly nests doesn't emit light but still stop hostile mobs from spawning. This will be beneficial for builders who want to keep the dark aesthetic of their builds but still want to be safe around them.

Players have also been asking for an anti hostile mob spawning beacon effect, and this could be an improvise to finally answer those player's wishes.
