Indent rules for end of protected type declarations

[JHertz5]

Is your feature request related to a problem? Please describe. I'd like a rule to correct the indentation of the end of protected type declarations, e.g.

package test is

  type flag_pt is protected
          end protected;

end package test;

package body test is

  type flag_pt is protected body
        end protected body;

end package body test;

should be corrected to

package test is

  type flag_pt is protected
  end protected;

end package test;

package body test is

  type flag_pt is protected body
  end protected body;

end package body test;

I've raised PR #1294 to resolve this issue.
