convert issue doesn't seem to be solved on windows

This code
```js
const imagemagickCli = require('imagemagick-cli')

//...
//...

imagemagickCli
.exec(`convert ${filename} -strip ${filename + '.min'}`)
.then(({ stdout, stderr }) => {
if (stderr) {
callback(Error('Error compressing ' + filename + '. ' + stderr))
} else {
// removes original and renames
fs.unlinkSync(filename)
fs.renameSync(filename + '.min', filename)
}
}).catch(err => {
callback(Error('Error compressing ' + filename + '. ' + err))
})
```

return this on windows

```
