feat: add colored and formatted logging

Add a custom logging setup function to add custom levels and custom
formatters (partly for future use with extended logging functionality).
Also implemented a basic colored formatter to make our logs nicer.

Also improved the handling of logging in external libraries, so now we
should only get WARNings or above.
