title: Seaborn despine with two y-scales (twinx)
body: <p>How can I keep <code>seaborn.despine</code> from putting both of my y-scales onto the left side of my plot?
  The best I've come up with so far is:</p>
  
  <pre><code>import matplotlib.pyplot as plt
  import seaborn as sns
  import numpy as np
  
  sns.set_style("white")
  
  fig, ax = plt.subplots()
  ax.plot(np.random.rand(10))
  ax2 =ax.twinx()
  ax2.plot(100*np.random.rand(10))
  sns.despine(ax=ax, right=True, left=True)
  sns.despine(ax=ax2, left=True, right=False)
  </code></pre>
  
  <p>But any other combination will either not despine the y-axes or put the right axis onto the left. </p>
  
  <p>Output of the above: (desired output has no spines, just numbers on left and right)</p>
