Watchdog timer for ATTiny1614 does not work for 4S and 8S

[BenthamITServices]

wdt_enable() works for all timeouts from WDTO_15MS to WDTO_2S but if WDTO_4S or WDTO_8S is used the Arduino IDE 2.3.2 produces the following error messages:

In file included from E:\Users\Steven\Documents\GitHub\Arduino_2\ATTiny1614\Blink_LED_on_PA2\Blink_LED_on_PA2.ino:3:0:

exit status 1

I can set the watchdog timer to 4S or 8S using the following code:
const uint8_t reset_timeout = 0xA; //or 0xB
wdt_enable(reset_timeout);

Hi!
When I read https://github.com/SpenceKonde/DxCore/blob/master/megaavr/extras/Ref_Reset.md correctly, you have to use WDT_PERIOD_8KCLK_gc for 8s and WDT_PERIOD_4KCLK_gc for 4s

(DxCore and megaTinyCore are quite similar and it is defined here: https://github.com/SpenceKonde/megaTinyCore/blob/7e836cd37f56b706c6a2f5c553ef1a6e97bf8ef9/megaavr/extras/ioheaders/iotn1614.h)
