This crate exposes seal's mluau C-Stack API bindings for seal FFI plugins.
You should use this crate instead of binding separately to mlua or mluau.
At the top of your seal_open_extern function, call sealbindings::initialize(ptr) with the
ptr to the LuauApi struct passed by seal.
After doing so, you can safely use the C-stack API methods in sealbindings::ffi.
