i.e. eliminating duplicate and unused entries from the palette

The process involves:

  • Search the palette for duplicate entries and eliminate them
  • Remove any entries from the palette that are never used in the image
  • Update the image data to reference the correct indices in the palette
  • Also update the alpha table, if present
  • Write some tests

This needs to be done with BitVec since indexed PNGs support bit depth < 8
