Specifically, the tests will ensure we all agree what we are trying to
accomplish / implement. We don't need to implement all possible combinations
now, but getting the basics would be helpful
Perhaps we can start with something simple like an input object like
Row 1
```json
{
"a" : {
"x": 55
},
"b": 42
}
```
Row 2
```
{
"a" : {
"x": "foo"
},
"b": 42
}
```
Where x is stored in a `typed_value` column
However, given that row2 has "x" as a string, it will need to be stored as a
variant I think
So then `variant_get(array, "a.x", Int32)` should return this I believe:
```
55
NULL
```
Maybe @scovich can checi me on that
