When the widest digit found in the image is a one, it is likely that a decimal separator is nearly as wide as this digit. Thus it cannot be recognized, because the decimal separator needs to be at most half as wide as the widest digit (before this commit). Thus add an additional pass over the digits for this special case. This pass comes after the existing recognition passes for the digit one, decimal separator, and minus sign. In the new pass, the width of the digit is ignored. This addresses GitHub issue #26.
