   With this PR, if I run:
   ```console
   $ archery benchmark  run /build/build-release/ --suite-filter 
arrow-value-parsing-benchmark --benchmark-filter "FloatParsing.DoubleType" 
--repetitions 20 --repetition-min-time=0.05 --output=t.json
   ```
   ... then the total runtime is less than 2 second and I get a results file 
like this:
   ```json
