P215 Scan: reconstructing the Canon P-215II file-tunnel transport

P215 Scan replaces the Canon imageFORMULA P-215II desktop scanning workflow on macOS and documents the scanner’s file-tunnel transport. Its reconstructed Auto Start mode exchanges SCSI command and data blocks through two files on an emulated USB volume; the main scanning mode uses the SANE canon_dr backend.
