Fix IDL parser for older lark

[andy31415]

It turns out lark had some backwards incompatible changes in meta placement first vs last argument when only @v_args(meta=True) is used.

Switch code to use inline as well, which seems consistent across versions.

While checking this, also fixed some mypy checks for static typing.
