better gzip(1) command line option compatibility: Support -l for gzip files

**Is your feature request related to a problem? Please describe.**
I'm experimenting with the "gzip" symlink on zstd binary and notice that there these compatibility options missing:

-n --no-name When compressing, do not save the original file name and time stamp by default. (The original name is always saved if the name had to be truncated.)

-l --list For each compressed file, list the following fields:
compressed size: size of the compressed file uncompressed size: size of the uncompressed file ratio: compression ratio (0.0% if unknown) uncompressed_name: name of the uncompressed file

While listing is available as an option, it just aborts with an error message:

```
zstd --format=gzip -l *gz
Frames Skips Compressed Uncompressed Ratio Check Filename
File "test-0.1.0.tar.gz" not compressed by zstd
```

**Describe the solution you'd like**

provide more drop-in compatibility when used via a symlink to "gzip" with the gzip command line options, as documented
here (and elsewhere): https://linux.die.net/man/1/gzip
