fixing column names while parsing deepracer log dataframe for new reward

[surojitchowdhury]

This fix helps to use deepracer log analysis Notebooks to use new_reward effectively.

Earlier the new_reward load was failing due to incorrect column names on Dataframe.

DeepRacerLog class in log.py is loading the logs using 'heading' name instead of 'yaw'.

Thank you for this PR. Can you check if all classes load with heading?

Hi,

Thanks for checking this PR. This change is only going to impact the class NewRewardUtils while loading new_rewards. No impact to any other classes. I have also raised a PR to add these new_reward processing in DeepRacer log analysis as part of the PR: aws-deepracer-community/deepracer-analysis#54.

I have tested that after the changes in log_utils.py as part of this PR, new_reward analysis works perfectly in Training Analysis Notebook.

Thanks,
Surojit

I looked back into this, and you are right -- some places things are loaded in with Yaw, others with Heading... Not sure how to fix this without breaking things elsewhere...
