Apply uncrustify formatting to all validity driver and test files
to pass the CI test_indent check.
Fix two pre-existing test failures:
- test-validity-capture: LED command blobs are 125 bytes, not 128
- test-validity-enroll: add 2-byte length prefix to test data to
match parser's expected format, fix empty-data assertion (parser
returns FALSE for data_len < 2)
All 41 tests pass, 0 failures.
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.
