Rebuild injection script using either PyInstaller, or as a Go project

[secureshellprotocol]

Its gotten too unweildly to add new features. The best course is either use PyInstaller to compile one unified python script, or to make it a fully fledged Go project, in order to keep it as one file, but make it relatively simple to add features and work on the codebase.
