Adds an image driver for the Samsung USB fingerprint sensor (04e8:7305) shipped in the Samsung Notebook 7 Spin (NP730QAA-K02US). The protocol was reverse-engineered from USB captures of the Windows vendor driver. The sensor is a 56x192 8-bit grayscale area sensor. Capture requires a 4-trigger sequence (3 pre-capture strip reads plus one full-frame read) and a vendor control-transfer bracket (heartbeat / response-length prime / wait-ready doorbell on EP0) around every bulk transfer. The sensor is physically a press sensor but is declared as FP_SCAN_TYPE_SWIPE and assembled from multiple frames via fpi_assemble_frames(), because NBIS's minutia extractor needs more ridge area than a single 56x192 frame provides. An inline comment near ASSEMBLE_STRIDE explains the rationale and references drivers/elan.c for precedent. A umockdev-based capture test is included.

History
LibFPrint was originally developed as part of an academic project at the University Of Manchester.
It aimed to hide the differences between consumer fingerprint scanners and provide a single uniform API to application developers.
Goal
The ultimate goal of the FPrint project is to make fingerprint scanners widely and easily usable under common Linux environments.
License
Section 6 of the license states that for compiled works that use
this library, such works must include LibFPrint copyright notices
alongside the copyright notices for the other parts of the work.
LibFPrint includes code from NIST's NBIS software distribution.
We include Bozorth3 from the US Export Controlled distribution, which we have determined to be fine being shipped in an open source project.
