Convert LI-HAR to k6 script

# LI-HAR to K6 script converter
A JavaScript package (node_module) exposing a function that takes a [_LI-HAR config_](li-har.spec.md) as parameter and returns a [_K6 script_](https://docs.k6.io/docs).  

### Requirements
The JS package should be a standalone package (node_module) and be runnable in a web browser environment (last 2 release Chrome, Firefox, Safari, Edge) as well as in Node.js (current LTS release).


#### Naive implementation
```javascript
// har-to-k6 lib
export function liHARToK6Script(liHARConfig) {
  return convertToK6Script(liHARConfig);
}
```

```javascript
// Usage
import { liHARToK6Script } from "har-to-k6";

const config = {
  log: {
    entries: [
      {
        request: {
          method: "POST",
          url: "http://test.loadimpact.com/login",
          headers: [
            {
              "name": "Content-Type",
              "value": "application/json"
            }
          ],
          postData: {
            "mimeType": "application/json",
            "text": "{\"user\":\"admin\",\"password\":\"123\"}"
          },
        },
      }
    ],
  }
};

liHARToK6Script(config);

// Output
`import http from "k6/http";

export default function() {
  var payload = JSON.stringify({ email: "aaa", password: "bbb" });
  http.post("http://test.loadimpact.com/login", payload, {
    headers: { "Content-Type": "application/json" }
  });
}`
```
