Allow predict_dataset_bands to be specified at predict time.

When using the model for inference, predict_dataset_bands must be defined at init time.

Describe the solution you'd like
I would like to be able to provide this at predict time, so that each call of predict can specify its own predict_dataset_bands.

The implementation should be relatively straight forward - whatever we currently do in the init can also be done at predict, with an extra argument accepted by the LightningInferenceModel at that time
