rewrite `if a != b, do: x, else: y` negations?

[novaugust]

Versions

• Elixir: use elixir --version
• Styler: use mix deps | grep locked | grep styler

Example Input

    x =
      if y[:z] != w do
        a
      else
        b
      end

right now we only rewrite ! and not operators. should we rewrite != to ==? what repercussions would there be for things like ! (a != b)?
