Licence is not querable

[EleniLouvari]

I would like to ask if licence can be included in the quearables.
Thank you

As can be seen here:
https://docs.pycsw.org/en/latest/metadata-model-reference.html

the license property in OGC API Records is mapped to the ISO-19115 otherConstraints property.

@EleniLouvari for your use case, we will need to add license support for STAC Collections and Items as well.
