title: can't open jp2 (from sentinel) with python rasterio,gdal
body: <p>I am trying to open the jp2 rasters products in python as raster, without success when we use the "raterio" and "gdal" packages.<br>
  I get this errors: </p>
  
  <pre><code>RasterioIOError: 'b4.jp2' not recognized as a supported file format.
  RuntimeError: `b4.jp2' not recognized as a supported file format.
  </code></pre>
  
  <p>I do manage to open them as a regular matrix with "glymur" package but then i lose the geo data.</p>
  
  <p>If someone know other pachage to open jp2 as raster i would be happy to know!</p>
  
  <p>I tried to follow this answer: <a href="https://stackoverflow.com/questions/56611197/python3-7-rasterio-library-cant-open-jp2">Python3.7 rasterio library cant open jp2</a> 
  installed fiona by conda
  or: <a href="https://gis.stackexchange.com/questions/250833/gdal-missing-jp2-driver-files-how-to-install-them/250837#250837">https://gis.stackexchange.com/questions/250833/gdal-missing-jp2-driver-files-how-to-install-them/250837#250837</a>
  and tried to install :<code>conda create -n mynewenv -c conda-forge gdal rasterio</code>
  but i still get the same errors.</p>
  
  <pre><code>b4 = rasterio.open('b4.jp2')
  b4 = rasterio.open('b4.jp2', driver= 'JP2OpenJPEG')
  </code></pre>
