SPM - Objective-C++ consumers fix

[3a4oT]

Workaround for Objective-C++ module which will consume this package, otherwise - Use of '@import' when C++ modules are disabled, consider using -fmodules and -fcxx-modules. Texture is coming..

@garrettmoon I guess we need to change dependencies in Package.swift, currently it pointed to my fork instead of Pinterest repository. Will, you able to tag the new PINCache (3.0.2??) so I can point it to something like

.package(url: "https://github.com/pinterest/PINCache.git", from: "3.0.2")

Wow, what a terrible code reviewer I am! Yes, please update to Pinterest and I'll publish a new release (working on it now).
