Fixes #3211. Adds the `--[no-]pass-through` flag which enables/disables pass-through mode. * `zstdcat`, `zcat`, and `gzcat` default to `--pass-through`. Pass-through mode can be disabled by passing `--no-pass-through`. * All other binaries default to not setting pass-through mode. However, we preserve the legacy behavior of enabling pass-through mode when writing to stdout with `-f` set, unless pass-through mode is explicitly disabled with `--no-pass-through`. Adds a new test for this behavior that should codify the behavior we want.
