Cleanup

Added variables to Makefiles to specify custom exports/ directory;
Split exception classes in Java & C#;
Added more comments;
Renamed library and Go package;
Removed real (pure) tests;
Added generate_lib.ps1 to generate import .lib for Windows (Swift);
Moved built Go libraries to exports/lib/;
Switch to hopefully faster Swift GitHub Action.

+<small>On Windows, you will also need to generate a .lib import library for the .dll. You can
+use `exports/generate_lib.ps1`
+for this, passing in the path to the DLL file. Execute this from a Visual Studio Developer shell before building the
+Swift project. Alternatively, you could use `objdump` and `llvm-dlltool`. You only need to update this if the list of
+exported symbols changes.</small>

+If you just want to copy over the C header file to the right directory for the modulemap in `CEduVpnCommon`, run:
+
+```shell
+make install-header
+```
+
+If you do not build this as part of the full repository, specify `EXPORTS_PATH="path/to/exports-folder"` when calling
+make. This folder must contain `platform.mk` and the `lib/` folder with built libraries and headers.
