unify package loader with lua's package.searchers

[Arnaz87]

Look into package.searchers and implement a searcher function to require packages as if they were regular lua modules. The packages should have a modules directory and in there the submodules to be required, for example a package with this structure:

• packages
  • my-package
    • actions
    • rules
    • modules
      • submodule

submodule would be maybe a helper functions or something like that, and in lua it would be used with require("my-package.submodule")

@Arnaz87 so we can load strings directly without intermediary file? https://www.lua.org/manual/5.3/manual.html#pdf-load
