Notes:

1. Do we test for append/extend for compound data? Can't find it.

[rly]

@mavaylon1 can you add a test for appending to a VectorData with a compound type array?

[rly]

Can you please check the failing coverage test where opt reqs=true? Why is it failing?

[mavaylon1]

Using the dim of the array cover both compound data and arrays that have the same dimension.
