Specifies a default value for the RAW_BODY environment variable

Motivation and Context

Fixes #37

• I have raised an issue to propose this change (required)
• My issue has received approval from the maintainers or lead with the design/approved label

How Has This Been Tested?

Before this change my function required the RAW_BODY environment variable to be defined otherwise an exception was thrown.
After making this change the RAW_BODY environment variable no longer has to be defined and assumes the value "false" if it is not specified.
