analogReadEnh1 not working on ATTiny1616

[schwghrt]

I (foolishly after reading your reference on analog inputs) chose a pin that is only connected to ADC1. (PC3/AIN9 on ADC1). I appreciate the fact that you did allow for the use of these pins.

I am able to use AnalogRead1(PIN_PC3) without issue. I wanted to use 10 bit resolution, but when I use AnalogReadEnh1(PIN_PC3) or AnalogReadEnh1(PIN_PC3,10) or AnalogReadEnh1(PIN_PC3,10, 0) I get the following compiler error:

[...]\AppData\Local\Arduino15\packages\megaTinyCore\hardware\megaavr\2.6.12\cores\megatinycore\wiring_analog.c:58:11: error: call to 'badArg' declared with attribute error:
badArg("analogRead called with constant pin that is not a valid analog pin");

I believe the issue is on line 1044 of wiring_analog.c. Specifically, the code calls "check_valid_analog_pin" instead of "check_valid_analog_pin1"

int32_t analogReadEnh1(uint8_t pin, uint8_t res, uint8_t gain) { 
  if (!(ADC1.CTRLA & 0x01)) return ADC_ENH_ERROR_DISABLED;  
    check_valid_enh_res(res);  
    check_valid_analog_pin(pin);

Yes, changing that code allows it to compile and seems to work. Although, I now realize 10-bit is the default setting.
