//This command has quite a complicated syntax, in theory it has 4 seperate syntaxes which are all variable:
//
//1: /firework clear - This clears all of the effects on a firework stack
//
//2: /firework power <int> - This changes the base power of a firework
//
//3: /firework fire - This 'fires' a copy of the firework held.
//3: /firework fire <int> - This 'fires' a number of copies of the firework held.
//3: /firework fire <other> - This 'fires' a copy of the firework held, in the direction you are looking, #easteregg
//
//4: /firework [meta] - This will add an effect to the firework stack held
//4: /firework color:<color> - The minimum you need to set an effect is 'color'
//4: Full Syntax: color:<color[,color,..]> [fade:<color[,color,..]>] [shape:<shape>] [effect:<effect[,effect]>]
//4: Possible Shapes: star, ball, large, creeper, burst
//4: Possible Effects trail, twinkle
