Option to make data files more user friendly

[jjkoehorst]

For downstream processing or reusability of crates it would be great to have a human readable structure.
Currently it uses the checksums that were provided by CWLProv and the output there is not very friendly:

This then results in a more combined structure in RO-Crate but if I would need a specific file for further processing in R for example I first need to process the JSON file before I would be able to identify the files. It also does not allow for browsing through the files and folders that is very useful if the data objects are shared among peers to get a better feeling of the data and structure without the need of fancy tooling to do this for you.

Which in turn does not really reflect the output

See #46. It offers a simple solution that may, however, lead to incorrect representations in case of clashes.

It's getting close! :) will check if the following structure is due to workflow output or something gets flattened.
Will let you know. The data folder was something I added #55
