------------------
- AnnotationManager function from_dict is called with an optional list of features
- Changed Polygon and Ellipse classes to include the list of features initialized by AnnotationManager
- to_dict function now only returns features in the dictionary that were asked for in the feature list
- Added `feature_multiplier` and `metric_unit` as inputs to apply to the features' name and value outputs.
- Added all features to `ellipse` and `polygon`.
- Features are now in camelCasing when output `to_dict`

------------------
- CDF-Main: Implement `filter` to allow filtering of annotations by feature values (aka gating).
- CDF-Main: Implement `from_contours`.
- CDF-Main: Implement `to_contours`.
- CDF-Main: Implement `from_dict`.
- CDF-Main: Implement `to_dict`. Includes rounding.
- CDF-Main: Implement `__len__`.
- CDF-Main: Implement `__iter__` and `__next__`.
- Add polygon annotation class.
- CDF-polygon: Implement `__eq__`
- CDF-polygon: Remove useless point
- Add ellipse annotation class.
- CDF-ellipse: Implement `__eq__`
- CDF-ellipse: Set all rotations between 0 and 90, flip radii if needed
- Renamed `CytoSmartDataFormat` to `AnnotationManager`
- Add `is_in_mask` for `Ellipse` and `Polygon`
- Add `min_overlap`-parameter in `to_dict` to apply masks to filter annotations
- Add `to_binary_mask` and `to_labeled_mask` for `AnnotationManager`, `Ellipse` and `Polygon`
- Add init-function `from_binary_mask` and `from_labeled_mask` to `AnnotationManager`
- Bugfix: Fixed a bug where `simplify_line` returns empty list when passing two points.
- Add option to to compress polygons in `to_dict()`.

- Add binary2contours

- make it possible to set n_iter to 0.

- Add iterative_downsampling for downsampling polygon points in 'naive' way

------------------
- Add json2bbox for ellipse with angle of rotation
