We have a structure type that implements UnmarshalCQL method.
We use it to unmarshal a user defined type. We also want to use the same struct for scanning an entire row.
There is StructScan method available in gocqlx for this purpose when iterating over rows, but no equivalent when doing a Select.
This commit introduces the possibility when doing select/get as well.

needed. Tools like dep make it easier by explicitly listing relevant
subpackages but the code needs to be downloaded anyway.
