Toggl Updates (to api.track.toggl.com) and FileNotFound Error

[svemagie]

Update TogglPy.py and downloader.ipynb to https://api.track.toggl.com/api/v8/ resp https://api.track.toggl.com/api/v2/

FileNotFound Error in: get_detailed_reports(workspace_id, since, until)
It doesn't make a difference if I create the corosponding empty file in advance or if there's no file.
FIXED: use full path instead of ~/
