CLI tool for wrapper generation

[haxscramper]

Even libclang does not have to be configured via code, so it makes sense to provide a simple command-line wrapper with limited configuration support.

• Setup wrapper project structure.
  • Automatically generate different types of configuration generator scripts - starting from no code at all (static configuration via .toml, .yaml or something else), to a little more involved calls to hcparse API or even "expose all internal details" link kind of setups for more annoying libraries.
• Setup main project configuration script Generated wrappers should support both static and dynamic linking #23
• Convert or wrap Cxx file via different analysis methods
• Generate and process doxygen XML?
