"friendable" piglins (using pigstep)

Unlike illagers, piglins have a way to be calmed. My idea is that by playing the new music disc pigstep on a jukebox, piglins within a 5 block radius will be "tamed". "Tamed" piglins will follow you around, and will attack any mobs that harm you in the nether. Tamed piglins will accompany you throughout the nether, and will only stop when you reach the nether portal. Opening chests near tamed piglins would not anger them.

Adding this feature will make the piglins have more personality and also, giving the the players much more reasons to travel to bastions.
