store new non-UTF-8 files raw and decode to deplay the contents

Dependencies

• [2] W4NSLQNG make text_encoding available to all of libpijul
• [3] IUH7IMWE Contributor license agreements
• [4] 246V5TYI decode existing files
• [5] NYOF5766 track file encoding in the record, including change text for file adds
• [6] SXEYMYF7 Fixing the bad changes in history (unfortunately, by rebooting).
• [7] VO5OQW4W Removing anyhow in libpijul
• [8] 6HNRL5RT detect non-utf8 text files
• [9] VMOYG7MK text file decoding for new files
