(devel/R-clipr) Updated 0.7.0 to 0.7.1

## clipr 0.7.1
- Call xsel with the `--output` flag, which prevents RStudio from
  hanging when calling clipr functions on a system running certain
  Linux window managers. Thank you to @cgillespie and @kevinushey for
  identifying the bug and the solution, and to @hannahcgunderman for
  help in testing.
