Support for finding Roaming directories under Windows

[abulka]

It would be nice if appdirs was updated to support finding roaming profile directory paths under Windows 10. I'm using a nodejs package that does something similar to appdirs called electron-log which interestingly, under windows, writes logs to %USERPROFILE%\AppData\Roaming\<app name>\log.log.

I'm trying to my align my nodejs and python log locations, and since appdirs doesn't support roaming paths, the closest I can get is

os.path.normpath(os.path.join(user_log_dir(), os.path.join('..', '..', 'Roaming', <app name>, LOG_FILENAME)))
