e13bintegrity element

The e13bintegrity element is present when codeline match testing
is not requested for front black and white images with acceptable
dimension and compressed data size test results. It contains the following
parts:
- raw
- Raw contains a floating point ratio of the number good characters to the number of characters expected in the codeline position of the image.
- broken
- Broken contains the number of broken MICR character pieces found in the codeline.
- score
- Score contains a floating point number between 0 and 10 (inclusive). This value is the Image Compliance estimate of the likelihood the image has well-formed E13B characters printed in the codeline position. A 10 indicates the E13B characters pass this test and are good. A 0 indicates the image fails this test and has a poorly formed or missing codeline. Values in between 0 and 10 indicate the image is marginal and may not have a usable codeline.
