ARROW-8390: [R] Expose schema unification features Recent changes made the default on dataset creation no longer scan all files and find a unified schema. This patch exposes an option on `$Inspect` and `$Finish` to reënable the old behavior. It also adds a wrapper around `UnifySchemas` for general use and adds that in `Dataset$create()` when making a `UnionDataset`. Dataset tests aren't really exercising the new options; hoping those are sufficiently tested in the C++ library. Closes #6890 from nealrichardson/unify-schemas Authored-by: Neal Richardson <neal.p.richardson@gmail.com> Signed-off-by: Neal Richardson <neal.p.richardson@gmail.com>
