[list] returns filepaths and dataset size of a dataset

[aaperis]

As a user I want to list the files in a dataset for which I have access to and the files therein and their sizes using the cli tool so that I can plan how to proceed with downloading files.

Description:

Finish the A/C from #388 that were not implemented in #415, i.e. filepaths should be returned instead of filenames so that they can used with ./sda-cli download and dataset size should be returned so that the user knows what to expect if the whole dataset is to be downloaded.

A/C;

• sda-cli list --config configfile --url <download.se> --dataset ABC gives the list of filepaths/fileID, their size and the dataset size
• It would also be nice to have the fileIDs in a 3rd column
• have size in bytes output as an option --bytes

Example output

$ sda-cli list [...]
<some metadata>
