Phillip and I had some discussion regarding whether asrab should be
merged back into asz80, however for the moment, I think it will be easier
to maintain if we keep them separate.

So it means that you re-invented (at least a part of) the wheal? The asrab is already included in the asxxxx 5.0 package... Can you please take a look to see if they can be merged or take a benefit from each other?

I believe all the files contained a pointer to the GPL in the header, so I am
under the impression that asrab is derived from source code covered under
the GPL license.

It is not a license question: both asxxxx and sdas are GPL V3.
