Jared Vacanti 5b34908a21 Add driver for SecuGen Hamster Pro 20 
Add support for the SecuGen Hamster Pro 20 (1162:2200), a 500 DPI
press-type optical scanner built around the SIDO020A sensor.

The protocol was reverse-engineered from USB packet captures. The
sensor is configured over I2C-tunneled vendor control transfers and
streams 956x688 raw frames over the bulk endpoint, read in 64KB
chunks so the standard pcap-based test tooling can record full
frames (the kernel usbmon interface truncates single URBs at
ring_size/5). Frames are processed with band compensation, an
edge-aware unsharp mask, a fixed-point bilinear downsample to
300x400, flat-field blending and directional sharpening, driven by
per-device factory calibration data read from the device firmware.
The fixed-point pipeline keeps the output bit-identical across
compilers and architectures for the image comparison test.

The sensor has no proximity hardware and its GET_STATUS request
always returns zeros, so finger presence is detected by polling
preview frames and comparing the mean brightness of the central
region against a calibration background frame.

Includes a umockdev capture/replay test with a reference image.
