Related to #42148 Add comprehensive support for struct array field type in the Go SDK, including data structure definitions, column operations, schema construction, and full test coverage. **Struct Array Column Implementation (`client/column/struct.go`)** - Add `columnStructArray` type to handle struct array fields - Implement `Column` interface methods: - `NewColumnStructArray()`: Create new struct array column from sub-fields - `Name()`, `Type()`: Basic metadata accessors - `Slice()`: Support slicing across all sub-fields - `FieldData()`: Convert to protobuf `StructArrayField` format - `Get()`: Retrieve struct values as `map[string]any` - `ValidateNullable()`, `CompactNullableValues()`: Nullable support - Placeholder implementations for unsupported operations (AppendValue, GetAsX, IsNull, AppendNull) **Struct Array Parsing (`client/column/columns.go`)** - Add `parseStructArrayData()` function to parse `StructArrayField` from protobuf - Update `FieldDataColumn()` to detect and parse struct array fields - Support range-based slicing for struct array data --------- Signed-off-by: Congqi Xia <congqi.xia@zilliz.com>
