"Clear Night" issue(no icon)

[DarkAssassinUA]

Hello!
Issue for Awtrix Weather ⛈️ + Forecast + 🌕️
As i said in issue name - there is no icon when weather status is "Clear night"
Empirically, I found out that my weather provider (GisMeteo)(used it bcs that provider give me more relevant weather in Ukraine) gives the status 'clear-night' - and icon not showing.

I looked into MQTT and found that
