Export practice sessions as file

Exporting practice sessions tracking at least to a text file (if not Excel) would be very helpful. The achievements and evolution could be followed on a computer (search within logs/plans, track achievements / speed improvement, etc) and comparation/identifying things that can be improved would be a lot easier.

Merged "Export practice logs to Markdown, CSV, or JSON" #558

"Hi, I would like to export practice logs to Markdown, CSV, or JSON to use in my own projects. Thanks!"

Yeah, was thinking of this too. For searching between practice sessions and organizing the practice. A CSV file would be easy to edit in excel.
