Add metadata to Plot Titles

[LydiaFrance]

Closes #123 #103

More complex than I first thought, but managed to create a file in callbacks which looks through the Hydra config files to provide information about training and evaluation within the plot title. Apologies that this is a larger PR than I intended.

Caveat...

I have tried my best here but there is probably a better method for scraping the correct info through Hydra. I am not the best at knowing what might be the most useful info and checking it grabbed the right thing. Given our time limits for the showcase might be good to check this at a later date.

Basically looks great.

Just a thought on the exact text. Is the Epoch always the number of epochs that the model is trained on? Or is it something else (e.g. the epoch the checkpoint was created on). Trying to work out whether it should be 'Epochs' as a total or 'Epoch' as a specific one.
