Support for ATmega 328 non-P?

[PaulRB]

Hi, is there a reason why the library does not support the non-P version of ATmega328?

With board selected as "ATmega328", sketches will not compile. To overcome this, I amended line 112 of LowPower.h as follows:
#if defined (__AVR_ATmega328P__) || defined (__AVR_ATmega328__) || defined (__AVR_ATmega168__)

The sketch below now compiles and uploads fine.

// **** INCLUDES *****
#include "LowPower.h"

void setup()
{
    Serial.begin(115200);
}

void loop() 
{
    Serial.println("Sleeping...");
    Serial.flush();
    // Enter power down state for 4 s with ADC and BOD module disabled
    LowPower.powerDown(SLEEP_4S, ADC_OFF, BOD_OFF);  
    
    Serial.println("Woke up...");
    Serial.flush();
    delay(4000);
}

I measure the current consumption during the sleeping periods at around 20-25uA vs. around 3.6mA when awake (8MHz internal clock, 3.3V). Not as low as a 328P, but not too bad at all!
