Description

Currently, when calling Scanner$create() on an arrow_dplyr_query the `projection` and `filter` arguments are ignored silently (since the dplyr query filters should be applied).

This is helpful for predicate pushdowns

One proposal is at https://gist.github.com/hannesmuehleisen/61d655bb345e0af374d10ca303894eef
