This allows the user to set an "active_listen" value in profile.yml to True (or "Yes") in order to change Naomi's listening behavior. Normally, you speak Naomi's keyphrase, Naomi responds with a high beep noise, then you speak your query, Naomi response with a low beep noise, then processes the request. Using passive listen, Naomi listens for your voice, then scans the entire block of audio for the keyword. If it detects the keyword, it passes the audio to the active listener, then finally returns the transcription. This pull request also fixes the issue that at some point the low beep got replaced with the high beep. I think it was when I was working on the Voice Activity Detector plugin.
This just adds an additional blank line between the import statements and the first function declaration to resolve a flake8 requirement (E302 - Surround top-level function and class definitions with two blank lines.)

Description
This allows the user to set an "passive_listen" value in profile.yml
to True (or "Yes") in order to change Naomi's listening behavior.
Normally, you speak Naomi's keyphrase, Naomi responds with a high
beep noise, then you speak your query, Naomi response with a low
beep noise, then processes the request.
Using passive listen, Naomi listens for your voice, then scans the
entire block of audio for the keyword. If it detects the keyword,
it passes the audio to the active listener, then finally returns
the transcription.
This pull request also fixes the issue that at some point the low
beep got replaced with the high beep. I think it was when I was
working on the Voice Activity Detector plugin.

Motivation and Context
This allows the user to interact with Naomi more naturally, by directly asking questions, rather than stating the wakeword, waiting for Naomi to answer, then stating the question.
How Has This Been Tested?
Tested on Raspberry Pi 3B+ running Raspbian Stretch using Pocketsphinx for both passive and active listening, WebRTC VAD for voice activity detection, and Flite SLT for text to speech.
