dswitkin 5cc1df3c92 Finished work on the local binarizer and renamed it to HybridBinarizer. It uses the old histogram for 1D and the new approach for 2D. The unit tests don't fully demonstrate how much better this is in real-world lighting, but it pretty much solves the situation of pointing at a QR Code for 30 seconds without scanning, due to a shadow or gradient.
HybridBinarizer is now the default across all the fast clients and the unit tests.

dswitkin 01eed5266e - Converted parts of the PDF 417 reader to use BitMatrix.
- Changed the PDF 417 detector to search the image more broadly, instead of assuming the barcode starts in the left 1/4 and ends in the right 1/4. We now get 8/23 on the real-world blackbox test, and we'll probably do even better with further improvements here.
- Added a quiet zone to two of the unit test images and updated a golden result for one of them. We now get 3/7 on the first test.
- Tried to fix some bugs in the upside down code but it still doesn't work.

dswitkin 2397216901 Added a few computer-generated PDF 417 barcodes to the blackbox tests. The current code doesn't seem to handle more advanced error correction modes.
