Review Comment:
```
functions.typedlit[mutable.Map[Int, Option[Int]]](mutable.Map(1 -> None))
```
in sql module return `MAP(1, CAST(NULL AS INT))`
in connect client module throw UnsupportedOperationException:
```
literal Map(1 -> None) not supported (yet).
java.lang.UnsupportedOperationException: literal Map(1 -> None) not
supported (yet).
