Add custom Augmentations - Albumentation Wrapper

[panagiotamoraiti]

Description

This PR adds custom Albumentations wrappers and additional augmentation classes to the rf-detr repository, addressing issue #81. The changes enable seamless integration of Albumentations transforms with bounding box support, as well as custom resizing and cropping augmentations missing from torchvision. A RandomSelect wrapper is also introduced to probabilistically select between two augmentation pipelines, increasing augmentation diversity.

This enhancement improves flexibility and configurability of data augmentations for object detection training pipelines.

Dependencies:

• Albumentations library

Additionally, original vs. augmented images were saved along with the bboxes for further inspection.

Hello @panagiotamoraiti

Thanks for working on this PR , I agree this is a very important part missing in the current setup .
Said that based on your changes i would suggest to also add copy-paste and mosaic as well to the augmentation options.

Thank you
