Issue Details

Description

The licenses of nvidia-cudnn-cu12==9.5.1.17 and nvidia-nccl-cu12==2.26.2 are not parsed by licensecheck >=2026.0.4, but they were parsed correctly by <=2026.0.1.

How to reproduce

echo nvidia-cudnn-cu12==9.5.1.17 > reqs.txt
echo nvidia-nccl-cu12==2.26.2 >> reqs.txt
licensecheck -r reqs.txt

Expected Behavior

With 2026.0.1, the output is correct:

$ uvx licensecheck==2026.0.1 -r reqs.txt

workaround

The workaround --ignore-packages 'nvidia-*', mentioned in #108, solves my issue, but I presume this is a symptom of a problem worth investigating.
