Analogy evaluation

[nicolasdugue]

Is your feature request related to a problem? Please describe.
The issue is related to a new feature :

• the SINr package should include a way to evaluate word embeddings using analogy datasets
• the SINr package should provide a way to compute a way to compute analogies for classic dense vectors (Word2vec, GloVe etc), but also for vectors such as the SINr ones -> other approaches than the

Describe the solution you'd like
This should be included in the sinr.text.evaluate package

• some functions shall allow to download analogy datasets
• a function shall allow to compute analogy such as in gensim
• a function is supposed to compute an analogy score for a dataset in particular
• some function should allow to try other ways to compute analogy when using SINr vectors

Requirements
Code should be tested using pyunit tests

Additional context
Coders can take a look at features and functions related to similarity evaluation
