targrep 0.10.0

Added

• .zip archives, through the stuffr-formats crate's zip container. A
  zip's members are searched like a tar's: per-member line numbers, -g,
  -T, binary detection, and one level of compression inside a member
  (access.log.1.gz in a zip). Stored, deflate, deflate64, bzip2, LZMA, xz
  and PPMd members are read. An encrypted member, a damaged one (CRC
  mismatch), or records the archive cannot account for are reported and
  make the run a 2. The members after an encrypted one are still searched.
• Unix compress (.Z, .tar.Z), through stuffr's decoder. Only as a
  whole file: a .Z member inside an archive is reported unread (exit 2)
  rather than searched as binary.
  • .Z records neither its length nor a checksum, so a truncated one reads
    as a shorter file with no error. A .Z with no match is still a 1, but
    trg prints a note on stderr saying the file could not vouch for its own
    end.

Fixed

• Errors from inside an archive did not say which archive: a sweep of a
  month of logs could print trg: tar entry: unexpected end of file and
  leave you to find it. Every such diagnostic now starts with the archive's
  path.
