Implement the capture command building infrastructure ported from python-validity's sensor.py and timeslot.py. This provides all the algorithms needed to construct sensor capture commands for calibration, enrollment, and identification modes. New components: - TLV chunk parsing (split/merge) for capture programs - Timeslot DSP instruction decoder (16 opcodes, 1-3 bytes each) - Timeslot table patching (Call repeat multiplication, factory cal) - Line Update Type 1 algorithm for 0xb5-class sensors - build_cmd_02(): main capture command builder - Factory bits parsing (subtag 3 cal values, subtag 7 cal data) - Frame averaging with multi-line deinterlacing - Calibration data processing (scale/accumulate/clip) - Clean slate format with SHA256 verification - Bitpack compression for factory calibration values - Finger ID mapping (FpFinger <-> VCSFW subtype 1-10) - LED control commands (glow_start_scan, glow_end_scan) - CaptureProg lookup table for firmware 6.x type-1 devices - OPEN_CAPTURE_SETUP state in the open SSM 27 unit tests covering all components. Full test suite: 36 OK, 0 Fail, 2 Skipped. |

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.
