Add `compressor`/`compressor_args` attributes to the `js_image_layer` rule, mirroring the `tar` rule from bazel-contrib/tar.bzl. When set, layers are compressed by an external program (e.g. `@pigz` for parallel gzip) via bsdtar's `--use-compress-program` instead of bsdtar's single-threaded built-in compressor. `compression` still selects the output file extension; `compressor` only swaps the program. No behavior change unless `compressor` is set. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
