WattleScript's Lua mode is missing some fields in `package` that "standard" Lua (PUC Lua) has. In particular, the lack of `package.preload`, `package.path`, and `package.searchers` prevents [Fennel](https://fennel-lang.org/) from working. I'm not sure whether this is partly a case of missing functionality or if the functionality is essentially all there and just needs to be exposed via `package`. I'm hoping it is all there because I don't see anything on the list of [differences](https://wattlescript.github.io/lua_differences) that would suggest this is a piece of functionality that's missing. I would like to submit a PR to address this, but am not sure I could add substantial functionality to the Lua mode's package functionality.
