Implements a Match-on-Host driver for the FocalTech FT9362 fingerprint
sensor (USB 0x2808:0xc652). The driver uses FpDevice with a custom
NCC-based matcher instead of NBIS, as the 64x80 sensor at 188 DPI
does not yield enough minutiae for reliable NBIS matching.
Enroll captures 10 images stored individually in FpPrint as a raw byte
array. Verify performs a single capture and computes normalized
cross-correlation with a ±10px search window against each enrolled
template; the maximum NCC score across all templates is compared against
a threshold of 0.50 to report match or no-match. Identify applies the
same NCC approach across all prints in the gallery and returns the
best-matching one above the threshold.
Add an umockdev driver test using a synthetic pcapng recording
(gradient image, NCC=1.0) that covers open, enroll (10 stages),
and verify.
