libfprint Goodix SPI Driver: reconstructing GDIX51C0 support

libfprint Goodix SPI Driver reconstructs support for the Goodix GDIX51C0 fingerprint sensor on Linux. It combines SPI transport, session and capture handling with a native ChicagoHS host-side biometric matcher, integrated through libfprint and fprintd patches. The source includes protocol research, algorithm comparison tools and deterministic tests.
