title: Is it possible to read ORC file to Spark Data Frame in sparklyr?
body: <p>I know that sparklyr has the following read file methods:</p>
  
  <ul>
  <li><code>spark_read_csv</code></li>
  <li><code>spark_read_parquet</code></li>
  <li><code>spark_read_json</code></li>
  </ul>
  
  <p>What about reading orc files? Is it supported yet by this library?</p>
  
  <p>I know I can use <a href="https://spark.apache.org/docs/2.1.0/api/R/read.orc.html" rel="nofollow noreferrer">read.orc</a> in SparkR or <a href="https://stackoverflow.com/questions/42955469/r-read-orc-file-from-s3">this solution</a>, but I'd like to keep my code in sparklyr.</p>
