   Hi, 
   I added some basic Frame functionality for the PythonAPI.
   
   Focused on:
   
   - Frame generation from pandas.DataFrame
   - write and read from csv incl. tests
   - rbind, cbind incl. tests
   - transform_encode and transform_apply incl. tests
   - hyperband test
   
   Currently all those tests and the previous ones (~110 in total) are passing 
on my side
   
   Sadly I forgot to turn off my auto-formatter, so right now it looks like 
there were quite some changes especially in 
   
   `src/main/python/systemds/context/systemds_context.py`
   
   real changes are pretty much only in read()
   
   `src/main/python/systemds/operator/operation_node.py`
   
   real changes in:
   - rbind(), cbind()
   - some parser conditions added for OutputType.FRAME
   - some checks/assertions
   
   
   if the formatting changes are an issue for those two files, let me know, 
then I'll try to find a proper way of fixing those.
   just wanted to add an initial pull-request so it can already be inspected.
   
   
   cheers,
   Bernhard Leder
