Goal is to improve separation between packages and utilities.
Can help with autocompletion/navigate nixpkgs faster.
Also it will help standardize how LUA_PATH is exported across packages,
so that one can more easily make lua changes across nixpkgs (for
instance changing where lua modules are installed).
* lua: generate packages from luarocks
* luarocks-nix: update
* removed packages already available in nixpkgs
* adressing reviews
update script can now accept another csv file as input with -c
* Remove obsolete comment
