title: Numpy Convert String Representation of Boolean Array To Boolean Array
body: <p>Is there a native numpy way to convert an array of string representations of booleans eg:</p>
  
  <pre><code>['True','False','True','False']
  </code></pre>
  
  <p>To an actual boolean array I can use for masking/indexing? I could do a for loop going through and rebuilding the array but for large arrays this is slow.</p>
