Support for array nested column identifiers and same-row modification

[matteofigus]

At the moment, it is possible to identify a row and delete the full row based on various identifier types - but not when nested within arrays.

Let's take the following example:

{ "foo": "bar", "list": [{ "customer_id": 12345 }, { "customer_id": 23456 } ]}
{ "foo": "baz", "list": [{ "customer_id": 23456 }, { "customer_id": 34567 } ]}

A desired output for deleting list.customer_id=23456 would be rewriting all the relevant rows when that would happen:

{ "foo": "bar", "list": [{ "customer_id": 12345 }]}
{ "foo": "baz", "list": [{ "customer_id": 34567 }]}

Pending questions:

• What's the desired output of an array becoming empty? Leaving it empty or full row deletion?
