Add 2FA support

[gdzevo]

Is there any chance to get 2FA support or at least update related documentation on https://docs.pcloud.com/
I made a choice to use pcloud because you had clients for most of systems, even for those that do not have GUI installed.

I also cannot use this client because of the lack of 2FA.

If I'm reading the debug log correctly, having 2FA enabled on the pCloud account and trying to use this client gives the error "NOTICE: pdiff.c:241 (function get_connected_socket): userinfo returned error 1141 Please provide 'deviceid'.", which sorta makes sense if 2FA is half-implemented already.

I found a "devices" table in the .pcloud/data.db SQLite database, but I don't know if that's related, and I can't be bothered to look any further. I'm going to do something more fun. :)

I would love to see this too... I would prefer to keep my cloud storage in sync with a local headless server of my own but I'm unwilling to abandon 2 factor to do so.

This is also a major concern for me. Support for 2FA for the command line client would be great.
