SPM Test target + Github Action to build and test (#596)

* SPM Test target + Github Action to build and test

Because the tests are XCTests `swift test` runs them first and then runs another batch of empty tests which results in "0 tests" at the end of the report - https://github.com/swiftlang/swift-package-manager/issues/8529#issuecomment-2815711345

* Fix dependency and library issues + handle mixed languages

`include` folder has to be next to the `*.c` file for it to work
