Add FiftyOne datamodule

[lumurillo]

What does this PR do?

Add a new datamodule that loads FiftyOne datasets. This implementation let MART delegate the data handling to FiftyOne, where the user can do data curation tasks.

This data handling would be agnostic to MART, because at the end here is adapted a torchvision dataset.

I set this implementation to be optional. The user can install the fiftyone dependencies by running:

pip install -e .[fiftyone]

Important:

• To create a dataset in FiftyOne, it's recommended to use the CLI feature: https://docs.voxel51.com/cli/index.html#create-datasets
• To launch the FiftyOne app: https://docs.voxel51.com/cli/index.html#launch-the-app

FiftyOne commands to load (index) datasets.

Use COCO-2017 as an example. Unfortunately, FiftyOne does not support person-keypoints annotations yet.

Download and load zoo datasets

fiftyone zoo datasets load \
coco-2017 \
-s train \
-n coco-2017-instances-train \
-k include_id=true label_types=detections,segmentations

fiftyone zoo datasets load \
coco-2017 \
-s validation \
-n coco-2017-instances-validation \
-k include_id=true label_types=detections,segmentations

Load local datasets

fiftyone datasets create \
--name coco-2017-instances-validation \
--dataset-dir /raid/datasets/coco/ \
--type fiftyone.types.COCODetectionDataset \
--kwargs \
data_path="val2017" \
labels_path=/raid/datasets/coco/annotations/instances_val2017.json \
persistent=true \
include_id=true

Use the FiftyOne datamodule

Is this for the for the example documentation?
