Remove unused dependencies

[Celebrate-future]

@SirOibaf Hi, I am a user of project se.kth.karamel:karamel-common:0.6. I found that its pom file introduced 49 dependencies. However, among them, 9 libraries (18%) have not been used by your project (the redundant dependencies are listed below). This PR helps se.kth.karamel:karamel-common:0.6 lose weight :) I have tested the revised configuration in my local environment. It is safe to remove the unused libraries.

Best regards
