Support for multi type arrays

[saty9]

It would be useful to support arrays with multiple data types like structured arrays https://numpy.org/doc/stable/user/basics.rec.html

This would be useful when dealing with for example timestamped data where you have a u64 timestamp in one column and x,y,z floats in 3 other columns.

Thanks. I don't think it's easy to support, but definitely worth considering.
