Binwrap slows execution down

My editor is executing `elm-format` a lot. It looks like `binwrap` is slowing down execution. Same effect with `npm` only. I think we need more comparisons on other systems and if `binwrap` is the cause we should look into something like the elm "no-deps" installer, which is using `npm` but looks like it isn't slowing execution down on my machine.

### 450ms vs 80ms

```shell

Reproduce the reported elm-format timings for the binwrap path and the alternate installed path, starting with the shell commands and measurements in the issue. Compare behavior across systems and inspect the linked installers/npm directory, including the no-deps installer. Done means identifying whether binwrap causes the slowdown and documenting a concrete direction based on those comparisons.
