small refactor for plotting experiment results

[bjuergens]

• changed plot and batchplot scripts to use TAP.
• Added option for smoothing to batch_generate_plot.py
• some minor changes to existing CLI paramters to both scripts

On a side note:

I use the following pipeline to look at simulation results

cd ~/dev/project/NeuroEvolution-CTRNN_new && python neuro_evolution_ctrnn/batch_generate_plot.py results/data/ --smooth 5 && cd results && python resuts_to_csv.py && libreoffice data.csv

This assumes the following:

• the venv is active
• the repository is located under ~/dev/project/NeuroEvolution-CTRNN_new
• the repository contains a softlink to the results - repository with the name results

Can be reviewed and merged now
