[I] Optimize StringView row decoding [arrow-rs]
alamb opened a new issue, #5945:
URL: https://github.com/apache/arrow-rs/issues/5945
**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
Part of https://github.com/apache/arrow-rs/issues/5374
@XiangpengHao implemented row format --> ByteView (StringView / BinaryView) encoding/decoing in https://github.com/apache/arrow-rs/pull/5922/files
**Describe the solution you'd like**
1. Add a benchmark for StringView to https://github.com/apache/arrow-rs/blob/master/arrow/benches/row_format.rs
2. Make the row conversion faster
**Describe alternatives you've considered**
@tustvold noted that a potential performance improvement https://github.com/apache/arrow-rs/pull/5922/files#r1650032068 -- namely to build the array directly rather than build a StringArray and then convert to StringView

take, as it seems that decoding string view is taking longer than it should be.
