Not detecting barcodes without successful scan

Thank you for taking over maintainership of this package!

I noticed the live_w_locator example has changed behavior between versions 0.0.2 and 0.0.3. Earlier, the scanner was painting green squares when it started noticing barcodes without successfully scanning them, i.e., onDetected callback is not called. Now, the green squares are only painted when a barcode is successfully scanned. So it seems the content of result.boxes for the Quagga.onProcessed callback behaves differently after version 0.0.3. Is this a regression?

To reproduce

• Compare the old behavior on https://serratus.github.io/quaggaJS/examples/live_w_locator.html to the live_w_locator example in master branch

Thank you Erik for the fix! I can confirm that it works.

Lessons learned today:

1. my computer’s webcam does in fact work well enough to at least recognize boxes
2. npm link + webpack dev server are an amazing combination
3. fixing what appear to be tiny lint errors may introduce a change to a function that has sweeping effects on the rest of the software, so don’t even think about changing a return value until you have a complete understanding of where that return value might be used. (somewhere in the result handling, someone is expecting decodeFromBoundingBoxes to return undefined, which in the code inherited, was not an explicit return, so i fixed the function to always return a value, but that’s not correct.)

0.0.6 should fix this issue
