feat: aliases for subcommands

[nik-rev]

I'm using this, I quite like it. thanks for making this!

I propose to add aliases for the 4 subcommands, since they're quite long to type. Descriptive names are nice, but when you need to type it a lot it's more comfortable to have short names as an option.

I like to alias ripunzip to rz.
So instead of ripunzip unzip-file I can just type rz uf

Help menu looks like this:

A tool to unzip an archive in parallel

Usage: ripunzip [OPTIONS] <COMMAND>

Commands:
  list-file   Lists a zip file [aliases: lf]
  unzip-file  Unzip a zip file [aliases: uf]
  list-uri    Lists a zip file from a URI [aliases: lu]
  unzip-uri   Unzips a zip file from a URI [aliases: uu]
  help        Print this message or the help of the given subcommand(s)

Options:
  -v, --verbose...  Increase logging verbosity
  -q, --quiet...    Decrease logging verbosity
  -h, --help        Print help (see more with '--help')
  -V, --version     Print version

If you'd like the alias to be hidden, that's also possible
