PJA 0.0.6

pjalsx, the zpaq-std plugin's fifth and last codec: subsampled JPEG-LS.

• pjalsx takes JPEG-LS whose components are subsampled (T.87's
  sampling factors: 4:2:0, 4:2:2, 4:1:1, T8SSE0's 2x4/2x1/1x2...), with
  no interleave or line interleave, lossless or near-lossless. Its block
  carries its own ZPAQL decoder (60,776 bytes), so any zpaq extracts the
  archive without the plugin.
• The family, in the order zpaq-std tries it: pjax, pja, pjall,
  pjals, pjalsx (codec indices 0 pja, 1 pjals, 2 pjax, 3 pjall,
  4 pjalsx). pja, pjals, pjax and pjall, their streams and their ZPAQL
  are 0.0.5's, byte for byte.
• zpaq-std -sat on 67 subsampled JPEG-LS files with zpaq-std's 79 files:
  1.16% smaller than with 0.0.5; plain zpaq 7.15 extracts every file.
  On JPEG-LS made from JPEG photos zpaq's own -m often wins, and
  zpaq-std keeps it.
• CI on every supported platform: Linux x86-64, x86 and AArch64, macOS
  arm64, Windows x64 and x86; the codec's streams are the same bytes on
  all of them.
• The pja command is the same as 0.0.2's (it has handled subsampled
  JPEG-LS since then).
