Hydra Integration and Downstream Support

[Pale-Blue-Dot-97]

Major PR that adds hydra integration and much better support for downstream uses.

Major Updates

• Closes Use the submitit_slurm plugin with hydra to handle SLURM distributed computing  #481: hydra support extends to use on SLURM via the submitit plugin. There are a few compromises with runner however to achieve this.
• Some objects are now instantiated via hydra such as the optimiser, criterion and lr_scheduler
• Closes Add a Downstream Module #458 by adding better support for downstream tasks (rather than a dedicated module). This is achieved by adding the FlexiSceneClassifier model in classifiers.py and restructuring MinervaPSP to be very flexible and dynamic.
• Closes Add Checkpointing Support #462 by adding full checkpointing support, including loading from checkpoints.
• Closes Selectively Apply Transforms to Images and Masks #497 by allowing users to define which transforms are applied to both image and mask modes of the data.
• Closes Support Python 3.12 #424 Support Python 3.12
