Bug in reading pubDate from TRD

[terotil]

When id3v2 field TRD is non-empty, dropcaster tries to parse pubDate from that field, but unfortunately there's a typo in the parse line and it is looking for nonexistent field TDR. I'm suggesting following change (fix typo and use v2.3 field names)

diff --git a/lib/dropcaster/item.rb b/lib/dropcaster/item.rb
index 323afa8..5b8df16 100644
--- a/lib/dropcaster/item.rb

       @uuid = Digest::SHA1.hexdigest(File.read(file_path))

+      if tag2.TRDA.blank?
         logger.info("#{file_path} has no pub date set, using the file's modification time")
         @pub_date = Time.parse(File.new(file_path).mtime.to_s)
       else
-        @pub_date = Time.parse(tag2.TDR)
+        @pub_date = Time.parse(tag2.TRDA)
       end
     end
   end
