title: Decompression 'SNAPPY' not available with fastparquet
body: <p>I am trying to use fastparquet to open a file, but I get the error:</p>
  
  <pre><code>RuntimeError: Decompression 'SNAPPY' not available.  Options: ['GZIP', 'UNCOMPRESSED']
  </code></pre>
  
  <p>I have the following installed and have rebooted my interpreter:</p>
  
  <pre><code>python                    3.6.5                hc3d631a_2  
  python-snappy             0.5.2                    py36_0    conda-forge
  snappy                    1.1.7                hbae5bb6_3  
  fastparquet               0.1.5                    py36_0    conda-forge
  </code></pre>
  
  <p>Everything downloaded smoothly. I didn't know if I needed snappy or python-snappy so I got one had no fix and got the other, still with no success. All related issues I have found are fixed when downloading snappy, but I am still getting this error with having two snappys! Any help would be appreciated.</p>
