[Zeek] Extract IP Header Options

Hi,

I was wondering is there an existing way in Zeek to log IP Header Options?
The conn log has a lot of the IP Header fields but not the IP Header
"Options" field data. Specifically looking at logging data related to CIPSO
packet labeling (reference:
https://tools.ietf.org/html/draft-ietf-cipso-ipsecurity-01).

If not, can anyone point me to a decent example of a bro script logging
similar data from the IP Header? (it's been quite a few years since I've
looked at bro scripts and I haven't found any examples doing something
similar to what I want)

Thank guys any information you can provide would be helpful!
