Description

Add struct and parsing to extract and store DNS additional section type OPT rdata.

I have a solution that adds a struct DNSRDataOPT, and a new type in enum DNSRData: OPT.
Parsing logic is also added to parser.rs that populates this data (similar to how DNSRDataSOA, SRV, SSHFP are populated).
Extracting and exposing this data allows for added logic that can reference different types of OPT rdata in the EDNS spec.

Note: this is closely related to / an extension of feature #7011.
I could easily submit this as part of 7011, but wasn't sure if you would want this as its own submission. Please advise.

As its own pull request will make it easier to review - being a smaller unit of work. Sounds like this might be a sub-task of #7011?

Yes this could be a sub task of 7011 - the changes are all related. I can also package this logic up as an extra commit for 7011, the changes aren't too extensive.
