  [BUG] Possible issue with direct import
  ```
  import graspologic
  dir(graspologic)
  ```
  returns 
  
  ```
  ['__builtins__',
   '__cached__',
   '__doc__',
   '__file__',
   '__loader__',
   '__name__',
   '__package__',
   '__path__',
   '__spec__',
   '__version',
   '__version__',
   'graspologic',
   'layouts',
   'models',
   'partition',
   'plot',
   'preprocessing',
   'subgraph',
   'version']
  ```
  
  and is missing lots of modules (align, cluster, datasets, embed, inference, match, nominate, pipeline, utils).
  Is this intentional?
