bug(plugin): plugin does not support nested sub groups for AIO client files

[ben-of-codecraft]

When using Imports for client files, only the first imports are inline into the code. This will create missing functions for files that imports.

Expected behavior

/// file:index.ts
import {module} from 'mymodule.ts';

/// mymodule.ts
import {utils} from 'utils.ts';

Success: built Lua should have inline export functions from mymodule.ts and utils.ts

The current state is it will only add functions 1 level deep, so module from mymodules would be inline successfully, but not utils.
