Proposition of improvement visualization

Cool :) I need to check it for memory leaks matplotlib is famous for. I had hard time eliminating memory leaks, especially from backtrader draw() module. That's why all figures are explicitly closed after each render call. When you run rendering for thousand times it is crucial.

@AdrianP- , added: https://github.com/Kismuz/btgym/blob/master/tests/render_memory_leak_test.ipynb I used it to catch memory leaks. Also useful when running DQN with big replay memory buffers. Pay attention to process/vmemory_usage_percent metric for BTgymServer process.
