Function extract_tar_bz2_if_new

pub fn extract_tar_bz2_if_new(
    rt: &mut RustRuntimeServices<'_>,
    deps: ExtractTarBz2Deps<VarClaimed>,
    file: &Path,
    file_version: &str,
) -> Result<PathBuf>

Extracts the given file into persistent_dir (or into std::env::current_dir(), if no persistent dir is available).

To avoid redundant unzips between pipeline runs, callers must provide a file_version string that identifies the current file. If the previous run already unzipped a zip with the given file_version, this function will return nearly instantaneously.
