targrep 0.9.0

Added

• bzip2 and lz4, detected from content like the other formats: .tar.bz2,
  .tar.lz4, bare .bz2 and .lz4 logs, and .bz2 or .lz4 members inside
  any archive, one level deep. Both decoders are pure Rust, so the static
  Linux builds gain no C dependency.
  • bzip2 reads every stream in the file, so archives written by pbzip2 or
    lbzip2 (one stream per chunk) are read to the end.
  • lz4 reads every frame in the file (cat a.lz4 b.lz4), the legacy
    lz4 -l format, and steps over a leading skippable frame. A skippable
    frame between two data frames is reported as an error (exit 2).
