Add SparkFun USB PID supplement

[zackees]

Summary

• add a SparkFun USB PID fetcher for VID 1b4f with separate first-party and supplemental tiers
• wire first-party SparkFun rows before generic USB-ID feeds and weak third-party rows after generic/first-party sources
• document SparkFun source caveats and add focused parser tests

Source notes

• SparkFun does not appear to publish a single public USB PID registry; sparkfun/usb-pid, sparkfun/usb-pids, and matching raw allocation-table paths return 404.
• First-party rows come from SparkFun-maintained Arduino board packages, product-repo board files, UF2 �oard_config.h, and SparkFun product CircuitPython descriptors.
• Weak supplemental rows come from PlatformIO �uild.hwids and Adafruit CircuitPython descriptors for SparkFun-named boards; they fill gaps only and do not override first-party rows.
• A live fetch emitted 37 first-party rows, 37 supplemental rows, and 49 combined gap-fill rows. Spot checks: 1b4f:9206 Pro Micro 5V/16MHz, 1b4f:f016 SAMD51 Thing Plus, 1b4f:0035 Pro Micro ESP32-C3, 1b4f:8d24 Qwiic Micro, weak-only 1b4f:0027 ESP32-S2 Thing Plus, weak-only 1b4f:002e Teensy MicroMod, and ambiguous 1b4f:002a LoRaSerial / nRF52840 Mini Breakout.
• SparkFun Apollo3 still has no SparkFun VID/PID rows in its package; Artemis/Apollo3 remains a CH340 bridge hint case. VID/PID rows are USB product metadata and do not prove fbuild support for boards missing from crates/fbuild-config/assets/boards.

Validation

📝 Walkthrough

Walkthrough

This PR adds a new fetch_sparkfun_usb_pids.py script that scrapes SparkFun USB VID/PID data from boards.txt, USB descriptor headers, PlatformIO, and CircuitPython sources across two tiers, merges them, and writes JSON output. It includes a pytest suite, README documentation, and workflow wiring in update-data.yml for fetch, merge, and summary steps.

Changes

SparkFun USB PID supplement

Layer / File(s)	Summary
Fetch script foundations online-data-tools/fetch_sparkfun_usb_pids.py	Defines module purpose, constants, source dataclasses/configuration, regex patterns, and string/merge helper utilities.
Source parsers online-data-tools/fetch_sparkfun_usb_pids.py	Implements parsers for boards.txt, USB descriptor text, and PlatformIO board JSON, filtering to SparkFun VID 1b4f.
Tiered collection logic online-data-tools/fetch_sparkfun_usb_pids.py	Adds GitHub tree-walking helpers and collect_first_party/collect_platformio/collect_circuitpython/collect_supplemental/collect functions that fetch, merge, and gap-fill across tiers.
CLI entrypoint online-data-tools/fetch_sparkfun_usb_pids.py	Implements main() parsing --tier/--out, writing sorted JSON output.
Test suite online-data-tools/test_sparkfun_usb_pids.py	Adds fixtures and tests covering boards.txt, descriptor, and PlatformIO parsing, tier-merge gap-filling, and main() CLI behavior.
Workflow wiring .github/workflows/update-data.yml	Adds tier-1/tier-4 fetch steps, conditionally includes their JSON in merge args, and extends the summary table.
README documentation online-data-tools/README.md	Documents the new script, SparkFun tier rules, Apollo3 handling, and the new test command.

Poem

A rabbit hopped through SparkFun's trees,
Gathering PIDs with greatest ease 🐰
Tier one first, then tier four weak,
Merged and sorted, JSON sleek.
Boards.txt, descriptors, hwids too —
Hop along, the data's true! 🥕
