Waspmote with smart water ions board high power consumption in deep sleep mode

[StasOmel]

It's about ~270 uA instead of ~30 uA.
Fix: pins to low state at the end of WaspSensorSWIons::OFF()
digitalWrite(DIGITAL2, LOW);
digitalWrite(DIGITAL5, LOW);
digitalWrite(DIGITAL4, LOW);
digitalWrite(DIGITAL3, LOW);
digitalWrite(DIGITAL1, LOW);

Thanks for your contribution!

After some tests, I've found out that this change fix power consumption issue, but it break measures (first two measures Ok, but for next voltage for all sensors is 0.0). I've made some additional changes and now it works OK (correct consumption and correct measure).
Here are my current ON and OFF functions:

void WaspSensorSWIons::ON(void)
{
	// Turn on the power switches in Waspmote
	PWR.setSensorPower(SENS_5V, SENS_ON);
	PWR.setSensorPower(SENS_3V3, SENS_ON);
	delay(1000);
	
	// These pins manage the analog multiplexor
	// Digital pin 2 is for selecting
	pinMode(DIGITAL2, OUTPUT);
	pinMode(DIGITAL5, OUTPUT);
	pinMode(DIGITAL4, OUTPUT);
	pinMode(DIGITAL3, OUTPUT);

	digitalWrite(DIGITAL2, HIGH);
	digitalWrite(DIGITAL5, HIGH);
	digitalWrite(DIGITAL4, HIGH);
	digitalWrite(DIGITAL3, HIGH);

	pinMode(DRDY, INPUT);
	delay(100);
	
	// Configure the ADC
	myADC.begin();
}

void WaspSensorSWIons::OFF(void)
{
	// Turn on the power switches in Waspmote
	PWR.setSensorPower(SENS_5V, SENS_OFF);
	PWR.setSensorPower(SENS_3V3, SENS_OFF);
	delay(100);
	// pinMode(DIGITAL2, INPUT);
	// pinMode(DIGITAL5, INPUT);
	// pinMode(DIGITAL4, INPUT);
	// pinMode(DIGITAL3, INPUT);
	// pinMode(DIGITAL1, INPUT); 
	
	// Disable SPI flag
	SPI.isSmartWaterIons = false;
	SPI.end();

	digitalWrite(DIGITAL2, LOW);
	digitalWrite(DIGITAL5, LOW);
	digitalWrite(DIGITAL4, LOW);
	digitalWrite(DIGITAL3, LOW);
	// digitalWrite(DIGITAL1, LOW);
}

Anyway, please check this.
