Sahi

- refactorized [Coco class](https://github.com/obss/sahi/blob/3ad54d682a8ab2c98abfd88f30c80a85c19d1eb1/sahi/utils/coco.py#L726), added [CocoVid class](https://github.com/obss/sahi/blob/3ad54d682a8ab2c98abfd88f30c80a85c19d1eb1/sahi/utils/coco.py#L1508)

- added [coco_error_analysis.py](https://github.com/obss/sahi/blob/main/scripts/coco_error_analysis.py) script:

bash
python scripts/coco_error_analysis.py results.json output/folder/directory --ann coco/annotation/path


will calculate coco error plots and export them to given output folder directory.

If you want to specify mAP result type, set it as `--types bbox mask`.

If you want to export extra mAP bar plots and annotation area stats add `--extraplots` argument.

If you want to specify area regions, set it as `--areas 1024 9216 10000000000`.

* fix a sliced prediction bug happening on small images

Major Updates
- refactorize main predict function:
bash
python scripts/predict.py --visual --source image/file/or/folder --model_path path/to/model --config_path path/to/config

will export predictions visuals to `runs/predict/exp` folder.
If you want to export prediction pickles and cropped predictions add `--pickle` and `--crop` arguments.
- add option to export coco json:
bash
python scripts/predict.py --coco_file path/to/coco/file --source coco/images/directory --model_path path/to/model --config_path path/to/config

will perform inference using provided coco file, then export results as a coco json file to `runs/predict/exp/results.json`
- add script for coco2yolov5 conversion:
bash
python scripts/coco2yolov5.py --coco_file path/to/coco/file --source coco/images/directory --train_split 0.9

will convert given coco dataset to yolov5 format and export to `runs/coco2yolov5/exp` folder .

Minor Updates
- add export_format to crop_object_predictions
- fix coco annotation serialization
- more generic coco handling
- add option to export visuals
- update ci/package testing workflows

* fix cli argument

* fix function argument

* add export format selection

- add coco to yolo conversion utility

- added merger for single predictions
