Direct call to S3 method from bit64

[MichaelChirico]

Here is a direct call to an S3 method

disk.frame/R/recommend_nchunks.r

Line 68 in e589d90

map(~bit64::as.integer64.character(.x)/1024^3) %>%

This will stop working in the future when this symbol is un-exported. Prefer calling the generic directly: as.integer64(), and letting S3 dispatch do its thing.

See r-lib/bit64#76
