fix: Added verbose flag for Lambda to emit shorter version of output

[akshayrane]

Issue #, if available: #236

Description of changes:
Added an optional flag verbose to the Lambda input set to true by default to support backward compatibility with current behavior. To shorten the output, we must add "verbose": false to the event passed as input.

This reduces the size of output as it emits the short version of the evaluated rules similar to the CLI output.

Sample event:

{
   "data": "<data>", 
   "rules": [
      "<rule1>", 
      "<rule2>", 
      ...],
   "verbose": false
}
