In our project we're using repository rules to download and uncompress prebuilt C++ libraries. Due to the large archive size we were evaluating different compression algorithms. One interesting candidate (which is also supported by CMake) is Zstandard. Right now it is not available within Bazel.

The Apache Commons Compress now supports zstd through the zstd-jni library. Unfortunately it relies on a native library.

I prepared a proof-of-concept branch with some shortcuts in gjasny/zstd-decompression and would like to ask if you'd consider adding support for Zstandard compression given the icky JNI implementation.

(With aircompressor there is native implementation available bit it lacks Big Endian and Stream support)
