should this be var rank = new int[length] then new ArrayDimensions(rank) and forgo the resizing?

And populate rank, before new ArrayDimensions, so TotalLength can be precomputed too. And ArrayDimensions can be a record.

GetArrayValues also calls GetArrayLength. Instead maybe GetArrayValues can return (JArray, ArrayDimensions), or it can take a `ArrayDimensions argument?
