Generating new Sample Data as this doesn't work

[AditModi]

make changes to Running the heartrate.py python script generates fictitious IoT messages from multiple userid values. The IoT rule sends the message to Firehose, which writes the data out to S3.

The script assumes that it has access to AWS CLI credentials and that boto3 is installed on the machine running the script.

The hearrate.py doesn't work as the sample data is invalid.
