Custom suscription group sorting

[ScriptSlayer0]

Describe your suggested feature

As a frequent user of Libretube, I would like this app to be able to sort the groups of subscribed channels to the user's liking, as many times when creating groups they are sorted in a strange way (I don't know how the current sorting system works), but I think it would be a great improvement for users in general. I understand that this can be complicated, that it requires a lot of resources and that the developers have the priority to fix and find the bugs, that's why I open this proposal.
