PJA 0.0.5

pjall, the zpaq-std plugin's fourth codec: lossless JPEG.

• pjall takes lossless JPEG (SOF3, Huffman): 2 to 16 bits, predictors
  1 to 7, a point transform, restarts, a height in a DNL. Its samples go
  through JPEG-LS's samples model, and its block carries its own ZPAQL
  decoder (30,508 bytes), so any zpaq extracts the archive without the
  plugin.
• The family, in the order zpaq-std tries it: pjax, pja, pjall,
  pjals (codec indices 0 pja, 1 pjals, 2 pjax, 3 pjall). pja, pjals
  and pjax, their streams and their ZPAQL are 0.0.4's, byte for byte.
• zpaq-std -sa on 96 lossless JPEGs (36 synthetic, 60 photos) with
  zpaq-std's own 79 files: 14.9% smaller than with 0.0.4; the photos come
  out at 29 to 74% of their size. Plain zpaq 7.15 extracts every file.
• The pja command is the same as 0.0.2's (it has handled lossless JPEG
  since then).
