Now infoRDS() reports all the meta-data from
.Internal(serializeInfoFromConn()).

Hi,
I am writing a test that consults the serialization version of an `.rds`
file.
An attractive way to get this is:
tools:::get_serialization_version() # reports just version
which calls
.Internal(serializeInfoFromConn() # reports much more
but neither is truly exported for public use.
Is there an official, exported way to get the serialization version? It is
possible to get this information with R code yourself, but it doesn't feel
very elegant.
If not, could we have this? It's pretty easy these days to acquire a
version 3 file, without real intent, which risks making the package require
R >= 3.5.
Thanks,
Jenny
