compression_stream calls only available on OS X 10.11 or newer

I just added DataCompression to a Swift 5 based SwiftPM tool this one but I am now getting errors stating:

'compression_stream_init' is only available on OS X 10.11 or newer
'compression_stream_destroy' is only available on OS X 10.11 or newer

Here's my Package.swift file content:

// swift-tools-version:5.0

import PackageDescription

let package = Package(

    platforms: [.macOS(.v10_12)],
    products: [

        .library(name: "AccioKit", type: .dynamic, targets: ["AccioKit"])
    ],

        )
    ]
)

Found a fix, but my fix will probably break Swift 4 compatiblity. See #16.

If you want to keep supporting Swift 4, you will want to add platform availability checks as suggested by Xcode. If you don't see the warnings, you probably need to delete the Xcode project file and regenerate it.

Sorry this took forever. If you have time, you may check version 3.6.0
