title: Shrink and anchor matplotlib colorbar
body: <p>How do I use colorbar attributes such as in this snippet:</p>
  <pre><code>import seaborn as sns
  
  uniform_data = np.random.rand(10, 12) # random data
  ax = sns.heatmap(uniform_data)
  
  cbar = ax.collections[0].colorbar
  
  plt.show()
  </code></pre>
  <p>To shrink the colorbar and put it to the bottom and anchored to the lower left corner (that is, NOT centered)?</p>
  <p>Something like this, but with the colorbar shrunk to, let's say 70% and anchored to the bottom left</p>

  <p>I am unsure how to search for the methods as <code>cbar.set_location()</code> is not available.</p>
