### Describe the bug, including details regarding any error messages, version, and platform. When using `MarshalJSON` on a `FixedSizeBinary`, I would expect that calling `UnmarshalJSON` on a `FixedSizeBinaryBuilder` with the produced JSON would read the original rows back into the builder. However right now these operations are not symmetrical, and an error is returned instead: ``` failed to unmarshal json: illegal base64 data at input byte 6 ``` This is because the `FixedSizeBinaryBuilder` is using `base64.RawStdEncoding` while the `json.Marshal` method is using `base64.StdEncoding`. It seems like we should change the `FixedSizeBinaryBuilder` implementation to match the `json.Marshal` call and also use `base64.StdEncoding`. I will open a pull request to fix this shortly. ### Component(s) Go -- This is an automated message from the Apache Git Service.
