Support ArraysOfArrays v1

[oschulz]

Hi! I maintain ArraysOfArrays.jl, which just had its v1.0 release, and I'm going through the downstream packages to offer compatibility PRs where they're needed — this is one of them.

What changed in ArraysOfArrays v1

The element type of VectorOfArrays and friends is now a view rather than a copy, several old constructors are deprecated, and nestedview is deprecated in favour of the array-of-arrays constructors.

What this PR changes

Just the compat entry:

-ArraysOfArrays = "0.6"
+ArraysOfArrays = "0.6, 1"

No source changes are needed. MergedArrays only touches two parts of the ArraysOfArrays API, and neither is affected by the v1 changes:

• ArraysOfArrays.VectorOfArrays(vec(arrays)), the nested-arrays constructor, which behaves the same in v1.
• Base.getindex(array::MergedArrayOfArrays, i::Integer) = collect(array.storage[i]), which collects the element — so the elements-are-now-views change is invisible here, and MergedArrayOfArrays keeps returning plain Arrays exactly as before.

Testing

I ran the test suite against both majors on Julia 1.12, with --depwarn=yes:

ArraysOfArrays	Result
0.6.6	Test Summary: MergedArrays.jl | Pass 27 | Total 27 — passed
1.0.2	Test Summary: MergedArrays.jl | Pass 27 | Total 27 — passed

No deprecation warnings in either configuration.

One note, and a small request

This repo's CompatHelper workflow is currently in the disabled_inactivity state, so no automated compat bump would have arrived for the v1 release — hence the manual PR.

If this looks good to you, would you be willing to tag a patch release (0.3.1) once it's merged? The registry resolves compat from released versions, so without a tag MergedArrays would still hold users back to ArraysOfArrays 0.6. Happy to answer any questions about the v1 changes if something does come up.
