mf4700-print-scan: reconstructing Canon MF4700 print and scan protocols

mf4700-print-scan reconstructs printing and scanning for Canon MF4700-series devices in a macOS app. Its C encoder emits UFR II LT jobs based on differences observed in Canon driver output, while an MFNP client registers the Mac and retrieves scanned pages. A format reference records CPCA packets, job structure and print-data encoding.
