Technical summary

Solaar lacks a complete Swap Fx/F-keys feature implementation for supported Logitech devices.

Expose the HID++ Swap Fx/F-keys feature as a readable/writable setting and wire it into Solaar feature discovery.

This issue is feature-specific, so implementation should depend on HID++ feature support rather than a device-name heuristic.

The snippet uses native project logic; the feature descriptor is read from the Solaar device before the Fn-key swap setting is registered. The helper result is consumed directly by the patched code path.

After applying the patch, keep the import smoke test for the affected package:

python3 -c "import solaar; print('smoke test OK')"
