Human-readable format as a separate artifact from the serializable version

[BatmanAoD]

The README says:

A more human readable format that is closer to a classical THIRDPARTY file and already has serde support is being actively sought.

I propose a different option: let the yaml (or other) formats be an "intermediate" format for final rendering (e.g. as a Markdown), and and don't bother supporting deserialization of the final rendered form. That way, --previous doesn't need to be able to use the rendered version, and the tool for rendering from a yaml to a markdown (or whatever) can even be completely separate from bundle-licenses itself.

I just created a fork and added a new output Format: which is "Text" https://github.com/max-huster/cargo-bundle-licenses
It looks something like this:
