[Question] Contributing a Swift Package Manager build

Hello,

I have been working on Swift Package Manager build of XNNPack, so far for Web Assembly (with options for scalar, simd, relaxed-simd). I plan to expand this to support at least arm64, maybe other targets too. Would it be interesting for the project for me to upstream this work? Or should I keep it in a fork?

The biggest potential challenge is that the downloaded deps (cpuinfo, pthreadpool, fxdiv) still need to be downloaded from somewhere, which isn't natively supported by SwiftPM unless they're also SwiftPM packages (I'm unaware of anyone vending these particular libraries currently via SwiftPM but they might exist).

Let me know what you think.
