   Arguably failing is better than silently truncating, but that puts us back at the original user report. I see our options as:
   
   1. Do nothing in the code; document a workflow of casting the `utf8` column to `binary`, then stripping out the `00`s yourself in R
   2. In arrow_to_vector, if a nul is hit, downcast to binary and proceed with conversion (raise a warning instead of erroring)
   3. Add a `skipNul`-like option (cf. https://stat.ethz.ch/R-manual/R-devel/library/base/html/readLines.html and others) and strip nulls if they're hit, raising a warning but keeping the result as a character vector.
