Robustness fixing should accept a simple dictionary where keys are perturbation names and values are proportions to apply to all entities for that perturbation

[luca-martial]

Currently we are passing perturbations as single params:

augment_robustness(conll_path = 'data.conll',
                   uppercase = {'PROBLEM':0.05, 'TEST':0.05, 'TREATMENT':0.05},
                   lowercase = {'PROBLEM':0.05, 'TEST':0.05, 'TREATMENT':0.05})

We should change this to a new parameter that accepts a perturbation map that looks like this:

detailed_proportions = {
   "uppercase": {'PROBLEM':0.05, 'TEST':0.05, 'TREATMENT':0.05},
   "lowercase": {'PROBLEM':0.05, 'TEST':0.05, 'TREATMENT':0.05},
   "title": {'PROBLEM':0.05, 'TEST':0.05, 'TREATMENT':0.05},
   "add_punctuation": {'PROBLEM':0.05, 'TEST':0.05, 'TREATMENT':0.05},
}

augment_robustness(conll_path = 'data.conll',
                   entity_perturbation_map = detailed_proportions)

we should also accept a more simple version of this in another parameter:

proportions= {
   "uppercase": 0.05,
   "lowercase":  0.05}

augment_robustness(conll_path = 'data.conll',
                   perturbation_map = proportions)
