**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*) --> The IPC writer typically tries to avoid writing unreferenced data, e.g. re-encoding offsets for StringArray, ListArray, etc... see `write_array_data`. Currently the IPC writer writes view data types as is, potentially including significant unreferenced data. **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> I think by default the IPC writer should at least invoke the [GC](https://docs.rs/arrow-array/latest/arrow_array/array/struct.GenericByteViewArray.html#method.gc) API, and potentially [deduplicate](https://docs.rs/arrow-array/latest/arrow_array/builder/struct.GenericByteViewBuilder.html#method.with_deduplicate_strings) them. **Describe alternatives you've considered** <!-- A clear and concise description of any alternative solutions or features you've considered. --> **Additional context** <!-- Add any other context or screenshots about the feature request here. --> -- This is an automated message from the Apache Git Service.
