Closes #420 @DanDeepPhase we can implement this pretty easily now. But if you have any comments on syntax or how this should work that would help. See the new tests...

In favour of https://github.com/rafaqz/DimensionalData.jl/pull/609 Which needs tests, and I forgot about. And I'm not really sure on the best syntax. Feedback appreciated.

It got merged to the branch yes, but the PR seems dead there's no reopen button Maybe that's just a phone app thing idk

It's just a little tricky getting the syntax right, if you want to take over find shing the PR that would help it along

Yeah probably we should do a `convert(Array, parent(lookup))` rather than just `parent(lookup)` so that there are no further expansions.

No `collect` does the right thing. Makie must be actually iterating with `iterate` somewhere. Would be good to find that and switch it to a broadcast. `iterate` and `eachindex` are...

Shouldn't `DiskGenerator` fix that? Maybe it's not being used somehow. I thought we had fixed this 😅

Oh right we didn't actually fix that 😭
