title: Easiest way to convert a string into a HashMap
body: <p>if I have some text in a String like:</p>
  
  <blockquote>
    <p>"abc=123,def=456,ghi=789"</p>
  </blockquote>
  
  <p>how could I create a populated <code>HashMap&lt;String,Int&gt;</code> object for it in the easiest, shortest amount of code possible in Kotlin?</p>
