This filter implements a fix for scanners that have some columns

starting with the first one down ch_offset pixels.

The Deinterlacer detects if data is in SANE RGB frame format (3 bytes/pixel)
or in Grayscale (1 byte/pixel).

The first ch_offset lines of data in the output are fudged so that even indexed
add odd indexed pixels will have the same value. This is necessary because
- the real pixel values of the columns that are shifted down are not
