plugins: preview-tui: sox as alternative for mediainfo

[vlappa]

For audio file I think sox gives a nicer preview then mediainfo does for audio files.

It seems that wav files are handles by the print_bin_info() function

print_bin_info() {
    printf -- "-------- \033[1;31mBinary file\033[0m --------\n"
    if exists sox; then
        soxi "$1"
    elif exists mediainfo; then
        mediainfo "$1"
    else
        file -b "$1"
    fi
}

That print_bin_info() function isn't just for audio files. It's for any binary files in general.
