Better logging #12
Description
Currently logging is done by println!/eprintln!. This is not ideal. A logging framework, such as breadcrumbs (https://github.com/IntegralPilot/breadcrumbs-rs), should be used to manage this instead. It should be ensured that there are no outputs to stdout in release mode, in debug mode logs from a runtime-configurable list of "channels" (or equivalent) can be displayed to help with debugging.
