[Suggestion] Use needle command via SwiftPM

[horita-yuya]

How about distribute generator exectable via Swift Package Manager? like this

In my project, we don't use Carthage only SwiftPM at this moment. So, we want to use needle via SwiftPM.

Homebrew?

This is a good option, but I have two projects which use needle with different version. I want to manage the version locally.

Example

In my project, cli/Package.swift exists.

// swift-tools-version:5.1
import PackageDescription

let package = Package(
    name: "CommandLines",
    dependencies: [
        .package(url: "https://github.com/yonaskolb/XcodeGen", from: "2.17.0"),
        .package(url: "https://github.com/horita-yuya/needle", .branch("master"))
    ]
)

Using the following command, I use needle via SwiftPM.

$ swift run --package-path cli -c release needle version
0.16.0

How about support this officially?

Thankyou.
