[R] Don't re-export S3 methods from bit64

[MichaelChirico]

arrow/r/R/reexports-bit64.R

Lines 18 to 22 in f872372

	#' @importFrom bit64 print.integer64
	bit64::print.integer64
	#' @importFrom bit64 str.integer64
	bit64::str.integer64

These methods are slated to be removed from {bit64}'s NAMESPACE. Is there a particular reason to re-export them like this?

FWIW, I don't see any other call sites for these functions on GitHub.

See r-lib/bit64#76.

Thanks for the heads up. It looks like they were introduced in #19954 to handle a special case. Do you have a timeline for releasing a new version without the exports to CRAN?

[MichaelChirico]

No, but I don't plan on releasing more frequently than 6 months cadence, and it's at least 3 releases before becoming an error, so at a minimum 18 months.
