Audio or Haptic Notification when a tag is successfully read

[AldrichW]

From a user perspective, I want to know whether a tag was successfully read as I hover the vWand across the aisles. This could be from a short audio notification (similar to when the phone uses its NFC chip) or haptic feedback ( note that this may mess with our knock control detection)

[AldrichW]

Acceptance Criteria:

• After opening the app and successfully connecting with the vWand, I should be able to read any number of subsequent NFC tags
• When the vWand successfully reads a tag, I should be notified by an abrupt and noticeable notification. This can be done by some short audio beep. Or a sub 1-second vibration.
• This notification should not interfere with our other service functionality (ie. Knock Detection).
