Support for other other container formats

Great work on the app, there are far too few encryption apps for android. Would it be an idea to add support for cryfs or gocryptfs considering the security concerns with encfs?

I have interest in support for gocryptfs too. Gocryptfs works on Linux and MacOS and cppcryptfs (Windows version of gocryptfs) is running on Windows, so now only Android is missing.
