[Feature Request]: More SDDM themes

[imtheabdi]

I've been using this SDDM theme https://github.com/Keyitdev/sddm-astronaut-theme for a good few months and today i went to it's Github page to get new updates and fixes and i saw that it has had a major update and it's no longer one theme but a series of themes now.

These themes look really good and actually match the aesthetic of the HyDE, so i suggest adding these themes to choose from during the first install since we only just have 2 options right now and these are all forked from Candy theme, one of the current options in HyDE right now.

Ops I forgot. I added a wrapper for sddm in the Hyde-cli you can just set any sddm themes with it. Will be adding it as native to HyDE

basically just add the themes in /usr/share/sddm/themes then it should just be available for selection
