Option? to ignore semver metadata after `_`

[pefeigl]

Hello!

We're trying to skopeo sync oci artifacts for use with helm. They are versioned according to semver, but also contain metadata (after the + character, which helm changes to an underscore _, see https://helm.sh/docs/chart_best_practices/conventions/#version-numbers). We've tried to use skopeo sync in combination with images-by-semver: to copy these, but skopeo does not actually find the version numbers that contain metadata after a _.

Is there any way to make this work, or will we need to remove the metadata from the semver version?

Thanks for any help with this, greetings, Peter
