title: R terra tif import colormap
body: <p>When importing a .tif raster with <code>terra::rast()</code>, also a colormap is imported. Is there any way to force the function to not import the colormap, or to set it to NULL to use the default plot color palette?</p>
  <p>You can see the color table with:</p>
  <pre><code>terra::coltab()
  </code></pre>
