License scan reports conjunctive rather than disjunctive license expression for slint v1.0.0

A recent scan using SCIO v32.1.0 of the code available at https://github.com/slint-ui/slint/archive/refs/tags/v1.0.0.tar.gz reported a declared license expression of gpl-3.0 AND proprietary-license even though the notices state that there is actually a choice of licenses.

from README.md:

## License

# Slint License

Slint is available under either a [proprietary license](LICENSES/LicenseRef-Slint-commercial.md)
or [GNU GPLv3](LICENSES/GPL-3.0-only.txt).

Third party licenses listed in the `LICENSES` folder also apply to parts of the product.

The either/or construction clearly indicates a disjunctive choice of licenses rather than a conjunctive combination of licenses. The correct license expression would be:
gpl-3.0 OR proprietary-license
