Extremely simplified single-file, 20 LOC version of https://tqdm.github.io/docs/tqdm/ for debugging tqdm bugs like https://github.com/tqdm/tqdm/issues/760 or dropping the full dependency

# Save as tqdm.py in project dir, then `from tqdm import tqdm; from tqdm.auto import tqdm` should pick up this class, if fails use export PYTHONPATH=.
