good job. this is a pre-requisite step toward integrating https://lib.rs/crates/tracing-log.

and we then need to add liberally many more logging information across both lychee-lib and lychee-bin.

@MichaIng, that's another one, which could impact the output of your pipelines. Would you mind testing the change before the next release? The PR got merged to master, so you should be able to build master and see if everything still works as expected now. Thanks! 🙏

Will do that.
