Remove GNU --binary option

There are specialized commands that can handle this (tr, dos2unit).
Adding such support to every command runs against the Unix philosphy.
Furthermore, Rust, for good reasons, does not support opening files
in binary or text mode, so such support (which is complex and platform
dependent) would have to be emulated.
