Build with new build system

[timburgess]

I'm experimenting with a Package.swift using the new build system. Interestingly, it generates static libraries by default but without any lib prefix so the library becomes Upsurge.a. A swiftmodule is also generated and as the Makefile has shown, the two files should be droppable into an end project.

I'm trying to build on Linux which of course will have issues with import Accelerate but these can now be wrapped in #if !os(Linux) C style.

The -module-name must be Upsurge but the only way I can get that at present is to have an Upsurge subdir inserted below Source.

And obviously if we can get a build happening here, then it all directly applies to HDF5Kit with a sysmodule definition for the hdf5 C library.
