Datamodule & Model for Clay v1 (#253)

- Execute the model from the `config.yaml` file.
- Incorporate support for diverse satellite sensor inputs such as sentinel-1-rtc, sentinel-2l2a, landsat, naip, and linz.
- Include a `metadata.yaml` file, which provides information about various sensors like wavelength, mean, and standard deviation for each band.
- Implement cls tokens into ClayMAE.
- Utilize DINO as a teacher to guide model embeddings.
- Enable dynamic loading of sensor batch data for model training.
