Eliminate the use of pandas when sorting on evaluations catwalk component

We would like to get rid of `SQLAlchemy` and use `psycopg3` directly. The first step towards that goal requires us to get rid of pandas and the evaluations catwalk component is the way to start.

We need to do the sorting while evaluating the performance of a model without pandas in all the current options: best, worst, and random.

The code to modify is on `catwalk.utils` $\rightarrow$ `sort_predictions_and_labels`, and `catwalk.evaluations`
