Add TiCoTransform

[guarin]

TiCo uses the BYOL transform for image augmentations. To make the method easier to use and more consistent with other methods, we should add a TiCoTransform that is a subclass of BYOLTransform and just add a new docstring for TiCo.

TODO

• Add TiCoTransform as subclass of BYOLTransform
• Update TiCo examples and benchmark code to use TiCoTransform instead of BYOLTransform
