Dual-license "X or Y" statement detected as AND instead of OR

[voidpetal]

Description

Dual-license statement "X or Y" is detected as X AND Y instead of X OR Y.
https://github.com/g-truc/glm/blob/master/copying.txt contains:
GLM is licensed under The Happy Bunny License or MIT License
followed by both full license texts. ScanCode outputs:
"detected_license_expression_spdx": "LicenseRef-scancode-happy-bunny AND MIT"

Expected: LicenseRef-scancode-happy-bunny OR MIT

How To Reproduce

curl -s "https://raw.githubusercontent.com/g-truc/glm/master/copying.txt" -o copying.txt
scancode --license --json-pp result.json copying.txt
cat result.json | grep detected_license_expression_spdx

System configuration

• OS: macOS
• ScanCode version: 32.5.0
• Installation: pip

@voidpetal Thanks! it is truly amazing to see this happy bunny thing used IRL!
Here the resolution is a new rule like that:

---
license_expression: happy-bunny OR mit
is_license_notice: yes
relevance: 100
---
licensed under The {{Happy Bunny License or MIT}} License

Hi @pombredanne, thanks for providing the resolution! I drafted a new PR with the changes: #5040 for your review when convenient. Thanks!
