/**
 * get_formatting - get formatting
 * Description: Searches through the given string, starting at a '%', and
 *              returns a pointer to a struct containing the given flags,
 *              width, precision, length, and type formats for the next
 *              argument. Will move the pointer of the string it is given.
 *              Will need the struct and its flags member freed.
 *
 * @fmt: Double pointer to the formatting string to look through.
 * @args: va_list containing the arguments given to _printf. Needed in
 *        case precision is specified with a '*'.
 * Return: Pointer to allocated and filled formatting struct.
