[NEOS-766] Add support for transforming array datatypes

[nickzelei]

If someone selects a transformer on a numeric[] column, it would be great if they we could generate values for that.

There are a few other considerations however:

1. min, max number of items in an array (generating)
   1. Standard relevant transformer inputs
2. When transforming, the standard transformers and their options apply.
   1. Maybe we start by always retaining the standard array length of the input

Maybe until we support this, we should filter out or only allow null, passthrough, or default for list datatypes.
