read_fst is from the package fst. The fileformat fst uses is a binary
format designed to be fast readable. It is a column oriented format and
compressed. So, to be able to work fst needs access to the file itself
and wont accept a file connection as functions like read.table an
Also, because it is a binary compressed format using a compression
method that is fast to read, compressing also to zip seems to defeat the
purpose of fst.
