Feature Request: Add "verbose" or "debug" option

[brianredbeard]

I'm currently have to perform a reconciliation loop over a set of files in a directory which requires repeatedly attempting to download content. Unfortunately, while I see the fileId and the name of individual files in the output, i don't see the folder or other data.

e.g.

...
{"Filename": "keys.ogg", "Type": "", "MimeType": "audio/ogg", "FileSize": 4562227}
Downloading (bytes)... 171706 / 171706
{"Filename": "notes.mid", "Type": "", "MimeType": "audio/unknown", "FileSize": 171706}
Downloading (bytes)... 5093014 / 5093014
{"Filename": "rhythm.ogg", "Type": "", "MimeType": "audio/ogg", "FileSize": 5093014}
Downloading (bytes)... 934 / 934
{"Filename": "song.ini", "Type": "", "MimeType": "application/octet-stream", "FileSize": 934}
Downloading (bytes)... 4555503 / 4555503
{"Filename": "song.ogg", "Type": "", "MimeType": "audio/ogg", "FileSize": 4555503}

In this situation it would be helpful to more easily identify content which was not retrieved. Honestly, i'm not really opinionated on the mechanism. I assume I could use the fileId information, but it would be challenging to rebuild the directory content on that alone.

Open to suggestions and flexible on how things get done. :D
