Prepare a conll-u 2 cdli-conll converter
Can be part of https://github.com/cdli-gh/CDLI-CoNLL-to-CoNLLU-Converter or made as a separate standalone tool.
- takes as input 1 or more conll-u text(s) and their older counterpart cdli-conll version
- merges column 1-4 from the cdli-conll version with column 5-7 of the conll-u version
- converts the conll-u id of the head field into the appropriate Cdli-conll format
We can later work on a converter that can process only conll-u, providing lemmata (without the full morphological annotations).
