extract

I was able to confirm that os.Create() will happily follow symlinks.

Although standard tools like tar will not likely allow you to add two files with the same name to an archive file, it's certainly easy enough to do in code. This means that we need to add an additional check before writing to a destination to make sure that it's not a symlink outside of the destination.

The vulnerab

Blocked By: wix/vscode-glean#97

Example:

class Foo extends Component {

  render() {
    return (<div>
      {this.props.foo.map((bar) => <div>{bar.x}</div>)}
    </div>)
  }
}

Current:

 const Foo = props => {
   const foo = useRef();
   const x = useRef();
   return <div>
       {foo.current.map(bar => <div>{x.current}</div>)}
 

With questions that come up for first time users.

Describe the bug
Please, add "overwrite" files in the destination option. Instead of adding *.duplicate1 files, I'd like lessmsi to overwrite files in the destination.

To Reproduce
Steps to reproduce the behavior:

1. Use lessmsi to extract some msi
2. Use lessmsi to extract the same msi
3. Observe *.duplicate1 files, and no option to overwrite instead

Expected behavior

Currently the code coverage is around 70%. Need help to write tests so as to obtain a code coverage above 90%
