New line at end of map required when multiple topic maps are used

[gabriel-ocp]

If you do not leave a blank line at the end of each topic map, it seems that when they are merged into the temporary file, the build will fail.

This can be rectified by adding in a new line after each map is read, in the merge code:

lib/ascii_binder/engine.rb:

    # topic map files are in the _topic_maps folder

    # create a combined temp file with all topic maps
    tf = Tempfile.new("#{TOPIC_MAP_FILENAME}")

    Dir.glob("#{topic_map_folder}/*.yml").each do |filename|
      lines = IO.read(filename)
      tf << lines
      tf.write "\n"
    end

I have replicated the issue with my local asciibinder build. Using @gabriel-ocp's container image with his updated version of asciibinder, I verified the fixes worked as expected.
