Add unpacking progress when unpacking game.zip on data deploy

Because the games get very large and it would be nice to see what unzip is up to, show the progress in regards to number of files processed and total number of files to process, as well as the progress on the current file.

Here is a snippet I created within 10-15 minutes but it doesn't work entirely. When a game is unpacked, some files seem to be broken and the game doesn't start at all. Needs some more time to debug.

unpack_zip_with_progress()
{
    local zip_file="$1"
    local out_dir="$2"

    n_files=$(unzip -Z -1 "$zip_file" | wc -l)
    counter=0

    for f in $(unzip -Z -1 "$zip_file"); do
        counter=$((counter + 1))

        mkdir -p "$out_dir/$(dirname "$f")"
        unzip -o -c "$zip_file" "$f" 2> /dev/null | \
            pv -cN "($counter/$n_files) $(basename "$f")" -s "$(unzip -Z "$zip_file" "$f" | \
            awk '{print $4}')" > "$out_dir/$f"
    done
}

Instead of unzip "$game_zip" -d "$target_ver_dir" > /dev/null in script/data.sh call unpack_zip_with_progress "$game_zip" "$target_ver_dir".

Feel free to grab this issue and fix the above command.
