Trying to robustly parse a string that will have key/value pairs separated
by three pipes, where each additional key/value (if more than one exists)
will be delineated by four more pipes.

    string = 'key_1|||value_1||||key_2|||value_2'
    regex = '((?:(?!\|\|\|).)+)(?:\|\|\|)((?:(?!\|\|\|).)+)(?:\|\|\|\|)?'

I am not convinced this is the most effective or safest, any opinions would
be greatly appreciated!
