Improving performance of animation example

[erikvansebille]

This PR provides an update t the animation example which improves performance by avoiding for-loops in polars frame for tails

In large output files (e.g. from https://github.com/Parcels-code/Drifter_campaign_prediction/blob/main/Matroos/run_dcsm7.py), this can reduce animation generation time from 2 hours to 6 minutes
