Pokemon classifier model & evaluation

[dmf95]

PR Brief: reviewing the model fitting & evaluation in pokemon_classifier.ipynb for visibility, feedback, and a baseline for us to work from.

• Re-jigged the structure of the repo a little - all of the analysis that was done is in analysis/dom/
• Added to the eda_dom.ipynb and created the first versions of a classifier
• Moved the model code into pokemon_classifier.ipynb, this should run end-to-end without any dependencies
• pokemon_classifier.ipynb: data-prep + model fitting & evaluation... RF classifier & LR classifier... with and without SMOTE.... with and without x-validation...
• note: not the cleanest code, could benefit from refactoring.
