**Data frame joins leveraging `r pkg("data.table")`**

## CRAN description
Extends `r pkg("data.table")` join functionality, lets it work with any data
frame class, and provides a familiar `x`/`y`-style interface, enabling broad use
across R. Offers NA-safe matching by default, on-the-fly column selection,
multiple match-handling on both sides, `x` or `y` row order, and a row origin
indicator. Performs inner, left, right, full, semi- and anti-joins with equality
and inequality conditions, plus cross joins. Specific support for `data.table`,
(grouped) tibble, and `sf`/`sfc` objects and their attributes; returns a plain
data frame otherwise. Avoids data-copying of inputs and outputs. Allows
displaying the `r pkg("data.table")` code instead of (or as well as) executing
it.
