> Implement [{{slice()}}, {{slice_head()}}, and {{slice_tail()}}|https://dplyr.tidyverse.org/reference/slice.html] methods for {{ArrowTabular}}, {{Dataset}}, and {{arrow_dplyr_query}} objects . I believe this should be relatively straightforward, using {{Take()}} to return only the specified rows. We already have a {{head()}} method which I believe we can reuse for {{slice_head()}}.
