Relationship to DomainSets.jl

[zsunberg]

I recently discovered DomainSets.jl. It contains some of the sets we need, for example cartesian products, etc. What should this package's relationship to DomainSets be? I see a few possibilities.

1. No relationship - we act like DomainSets doesn't exist (but perhaps learn from it)
2. We maintain compatibility in case someone wants to use things from DomainSets, but also re-implement the functionality that we want here.
3. We use them as a base package for our interface and encourage using their sets in most cases, and only implement a few things that they don't provide (i.e. we would probably get rid of our product and use theirs.)
4. We re-export some of their sets like we do with IntervalSets (this seems bad)
5. We archive this package because DomainSets provides everything we need.

I wish I could have known that package earlier 😭

#3 seems to be more appealing to me. We can archive this package and add those that are not provided into CommonRLInterfaces.jl.

Yes, it is a pretty nice package, but doesn't have some things that we want, like rand and clamp, so we will have to work out how to integrate with it.
