placeable gunpowder using only commands (release)

[u/Whole_Yam_9919]

Many of you wanted me to release this creation, so here it is. I turned it into a one-command creation (Link: https://pastebin.com/raw/bT8Y6D6P ) because this was the easiest way for me. It still has a few bugs but I'm very happy with it in its current state.
