proposal: add `--fix` to `one-var`

// one-var: ["error", "never"]
const foo = 0,
  bar = 1;

can be fixed to:

const foo = 0;
const bar = 1;

I’m taking a look at this, although I’m only going to attempt fixes for cases where the two var declarations are next to each other (var a = 2; var b = 3, not var a = 2; for (var b in foo) {})

No worries, thanks for attempting it!
