Code Review
This pull request introduces the ValueBitmaskFilter class to support filtering cells by a value bitmask, along with corresponding unit tests. The reviewer pointed out that the _to_dict method incorrectly returns an instantiated protobuf message (data_v2_pb2.ValueBitmask) instead of a plain dictionary, which is inconsistent with other filters and could cause a NameError. Suggestions were provided to return a plain dictionary representation and to update the unit tests accordingly.

The _to_dict method should return a plain dictionary representation of the filter rather than instantiating a protobuf message (data_v2_pb2.ValueBitmask). Returning a protobuf message inside _to_dict is inconsistent with other filters, can cause NameError if data_v2_pb2 is not imported in this module, and defeats the purpose of a dictionary representation.
Instead, return a nested dictionary {"mask": self.mask} for the value_bitmask_filter key.

| return {"value_bitmask_filter": data_v2_pb2.ValueBitmask(mask=self.mask)} | |
| def _to_dict(self) -> dict[str, Any]: | |
| """Converts the row filter to a dict representation.""" | |
| return {"value_bitmask_filter": {"mask": self.mask}} |

Update the test to assert against the plain dictionary representation returned by _to_dict(), which avoids the need to import data_v2_pb2 locally.

| mask = b"\xaa" * 8 | |
| row_filter = self._target_class()(mask) | |
| expected = {"value_bitmask_filter": data_v2_pb2.ValueBitmask(mask=mask)} | |
| assert row_filter._to_dict() == expected | |
| def test_to_dict(self): | |
| mask = bytes([0xaa]) * 8 | |
| row_filter = self._target_class()(mask) | |
| expected = {"value_bitmask_filter": {"mask": mask}} | |
| assert row_filter._to_dict() == expected |
