Elytra fuel

Allow for players to load their elytra with a new substance made from gunpowder and netherrack to make a slow burning fuel thatd give them a boost in the air as long as they use their secondary action(on xbox its left trigger) as if they had a considtand fire work rocket behind them. Draw backs for this use would be mildly quicker degradation of the elytra requiring more frequent repair or mending. Itd be useful as a way to free a bit of space in the players inventory. I'd also suggest a new form of mob to obtain gunpowder from or make a villager who sells it as its insanely hard to come by with just creepers witches and gasts whomever always die over lava and witches are very rare to find randomly. Creepers are also an unreliable source making elytra travel almost unworthy it.
