**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> I would like to have `FixedSizeBinary` columns be serialized by the JSON writer as HEX, as they are for the CSV writer. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> Columns that are `FixedSizeBinary` be serialized as HEX strings. The CSV writer defaults to the default arrow-array formatter, which does this: https://github.com/apache/arrow-rs/blob/master/arrow-cast/src/display.rs#L746-L754 **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> Alternatively, I could change my queries to potentially cast the column I am querying for, so this isn't a deal breaker for me, but I feel as though since the CSV and default formatters do this for me, the JSON should as well. **Additional context** <!-- Add any other context or screenshots about the feature request here. --> The error returned originates from here: https://github.com/apache/arrow-rs/blob/master/arrow-json/src/writer/encoder.rs#L128 -- This is an automated message from the Apache Git Service.
