Improve show methods

[rwood-97]

Summary

Currently we have some very basic "show" methods for veiwing results. This is good for a quick look but would be better if we had some more advanced tools for visualising our results as part of the MapReader library.

Fixes #341
Address #478 - removed the utils.py file from annotate

Describe your changes

• Updates the show methods in images.py, runner_base.py and rec_runner_base.py and adds explore_xx methods in each of these classes. Explore uses geopandas explore to create an interactive visualisation of results.
• Also adds a check_georeferencing method ot the runners as this is needed to ensure we can convert to geo coords and therefore use the explore methods.
• Adds infer_coords_from_patches method in images.py which uses patches to infer parent coords. This is for e.g. if you have loaded patches via the load_patches method and only added patch metadata (e.g. predictions).
• Updates the way in which metrics are stored in classifier.py - now instead of train_loss_epoch and train_fscore_epoch as the key for a dict, we have nested dict with keys of train, val, etc and then within that keys of loss, fscore etc.
• This enables simplification of the plot_metrics method, users now pass a list of metrics to plot (e.g. "loss", "fscore_micro", etc) and it will plot by default all phases. Can tell it just to plot for one phase by passing the phases argument.
• I moved initialise model to the top of the file because it made sense to be grouped with the initialise_optimiser, initialise_scheduler etc methods.

Using the show_patches method:

Using the explore_patches method:

Using explore_predictions method (i.e. the equivalent to explore_patches but for text spotting):
