Update dependency and fix deprecation (#43)

I just noticed that TerminalLoggers holds back LeftChildRightSiblingTrees. This PR bumps the dependency and adds a CompatHelper setup to automate such updates in the future.

Moreover, when running the tests a deprecation warning turned up which I fixed.
