Winter Nord inspired themes for lemmy-ui

Hey everyone. I made two themes inspired and based off the winternord theme some of you may have seen already in your instances. One is a darker, more contrasty theme (icy-nord-darker) based on the other (icy-nord). They are very simple, but they do fix some issues I had with winternord, such as some text being very hard to read because of its colour, or the background image often interfering with the foreground and making it hard to read stuff.

Let me know what you think, any suggestions, what you like, and what you dislike.
