Added
* Integrated the clin_nlp_metrics package in this repository, specifically in `clinlp.metrics.ie`
* Support for non-binary qualifier in the Context Algorithm (e.g. 'Change', with values Decreasing, Stable and Increasing)
* Support for bidirectional qualifier patterns
Changed
* Moved all components related to information extraction to `clinlp.ie`. Please update imports accordingly (e.g. `from clinlp.ie import Term`).
* Updated the framework for qualifiers, to now have three qualifier classes: Presence, Temporality and Experiencer. For more details, see docs.
