scales 1.0.0 release to break `print.pprc()` function

[dpseidel]

The upcoming scales 1.0.0 release is introducing a generic number formatter to power the formatting functions like ordinal() which voteogram imports. The new formatter expects numerics and fails when passed a character string. Based upon our revdep checks, this will break your roll_call() function which passes the numeric specified by the user in the number argument as a character to the print.pprc() which calls scales::ordinal().

We expect to release shortly and wanted to give you a heads up. Let me know if I can offer more clarity on the change.
