Placing fire with a fire charge played item.firecharge.use at the flint and steel's pitch (nextFloat * 0.4 + 0.8, one draw). FireChargeItem.playSound uses (nextFloat - nextFloat) * 0.2 + 1.0, two draws from the level random. The pitch is now horizon_client::items::fire_starter_pitch, checked against the real FireChargeItem.playSound by tools/test_fire_starter_sound_parity.py.
