Skulkmites Spawn to Hunt Sneaking Players

Currently, the deep dark is almost zero threat if you have the patience to sneak through the entire area. This leads to the biome being more tedious than challenging. Skulkmites could be the deep dark's eyes, forcing slower players to move. Skulkmites would occasionally spawn on top of skulk blocks and chase the player (or any other mobs) like a silverfish or endermite. The mites themselves would be completely silent, even when taking damage, but they force noise out of players by damaging them or forcing them to run. Additionally, skulkmites would speed up the natural spread of skulk by killing or forcing noise out of other mobs for xp to grow the colony.
