title: TypeWriter - Filter classes or properties without a given attribute
body: <p>Using a Typewriter .tst file it is possible to only include Properties with a certain attribute using a <code>$Properties([MyAttr])</code> filter. </p>
  
  <p>Like this for example:</p>
  
  <pre><code>export class $Name{
          $Properties([MyAttr])[
          public $name: $Type = $Type[$Default];]
      }
  </code></pre>
  
  <p><strong>Is it possible to include all properties <em>except</em> those with the given attribute?</strong> </p>
  
  <p>Something like this maybe:</p>
  
  <pre><code>export class $Name{
          $Properties(![TsIgnore])[               //but this doesnt work!!
          public $name: $Type = $Type[$Default];]
      }
  </code></pre>
  
  <p>I've tried what I can think of <code>![TsIgnore]</code>, <code>[!TsIgnore]</code>, etc. but none work. Also cannot find anything in the <a href="https://frhagn.github.io/Typewriter/" rel="nofollow noreferrer">docs</a></p>
