title: How to change the crs of a raster with rasterio?
body: <p>I am trying to change the CRS of a raster tif file. When I assign new CRS using the following code:</p>
  
  <pre><code>with rio.open(solar_path, mode='r+') as raster:
      raster.crs = rio.crs.CRS({'init': 'epsg:27700'})
      show((raster, 1))
      print(raster.crs)
  </code></pre>
  
  <p>The print function returns 'EPSG:27700', however after plotting the image the CRS clearly hasn't change?</p>
