Added metrics support for multiclass-multioutput classification

Fix for #3453 
Ping @arjoly . Added support for `zero_one_loss` and `accuracy_score`

Here you are testing that a mix of multioutput-multiclass format and multilabel-sequence (deprecated) format reaises an error. It's similar to what is done in https://github.com/akshayah3/scikit-learn/blob/metrics/sklearn/metrics/tests/test_common.py#L620

What I was proposing was to enhance the tests for that particular assertion or to create a new one.
