RFC: Removing lua bindings

[RuhiRG]

Since the refactors for #35, the lua bindings to functions have stopped working. This is expected, the lua bindings relied on objects being constructed in C++ and provided to the lua environment. With pyseams however, this is no longer required.

As currently written, the functions.lua files are used to call C++ functions, but they can be removed, the CLI should be used with the lua variables and yaml files to run the analysis in functions.lua.

For backwards compatibility I would propose adding these C++ only workflows to the CLI while removing the lua bindings.
