Make a data.frame with pre-serialized integer64 columns
Source:R/serialize-bit64.R
serialize_bit64.Rdinteger64 types do not dput wells with hexNumeric. Instead, we serialize and
then unserialize them cf truecluster/bit64#27 and store that as one expression per column
This makes the resulting data.frame awkward, but it will be recorded by dput in a
way that does get read back in faithfully (so long as the expression isn't quoted).
