Adding support for Centrifuge staking rewards

[lucasvo]

This PR adds support for Centrifuge to the rewards collector. I also modified the script to allow customizing the output directory.

If I run your version locally I get the following errors. The output in the terminal is still produced properly, I guess there is some bug in creating the folder or writing files into a non-existing folder (?). Could you please check.

@jonasW3F yeah I did not add "out" to git but had it in the config - I added the folder, another way to fix this would be to just leave the prefix empty in the config. Let me if this solution is fine!
