 The attachments consist of a patch for the Freesat Huffman code
 decompressor and a replacement for the header file.  Since the header is
 completely replaced and quite large I'm including it as compressed file on
 its own rather than as a patch.  The changes add approximately 50% more
 entries to the tables but I've taken the opportunity to reorganise them to
 use an index file to reduce the size of the tables and speed up
 decompression.  With these changes virtually all the current Freesat EIT
 decompresses successfully but there are still lots of gaps in the the
 tables so inevitably there will be omissions and errors.

 Note: the Freesat EIT, as with Freeview in the UK, appears to be
 transmitted in full on each transponder so passive scanning while
 recording from any channel will normally be sufficient.
