lignah fbaa97eaeb drivers: add initial Samsung 730B image driver 
Add an experimental driver for the Samsung 730B USB fingerprint sensor
(04e8:730b).

The implementation is based on reverse engineering of the Windows traffic
and a Python prototype:
- repo: https://github.com/lignah/samsung-730b-reverse
- script: scripts/samsung_730b_v1_3.py

Implemented pieces:
- device init sequence (0xC3 control + A9/A8 bulk writes)
- image capture using 0xCA control and 256-byte bulk chunks
- image layout: 112x96 at offset 180 in the raw buffer
- basic image-based finger detection (short probe + ff ratio heuristic)

The driver currently exposes the device as a press-type image sensor and
can capture usable fingerprints via libfprint.

Known limitations:
- Finger detection and capture work, but fprintd enrollment UX is still
  rough (minutiae detection sometimes fails, and higher-level behavior
  needs tuning).
- The driver is marked experimental on purpose; further iteration with
  libfprint/fprintd maintainers is expected.

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.
