Adds an option for lazy decoding of query results. Currently, all values in a query result row are decoded from protobuf values to plain Java objects at the moment that the result set is advanced to the next row. This means that all values are decoded, regardless whether the application actually fetches these or not. Lazy decoding also enables the possibility for (internal) consumers of a result set to access the protobuf value before it is converted to a plain Java object. This for example allows ChecksumResultSet to calculate the checksum based on the protobuf value, instead of a Java object, which can be more efficient.

* refactor: move inner classes to top level Move the gRPC-related inner classes from AbstractResultSet to top-level classes, so they are easier to modify and maintain. This change only contains modifications that are needed to move these inner classes. There are no functional changes. * feat: support lazy decoding of query results (#2847) * feat: support lazy decoding of query results Adds an option for lazy decoding of query results.
