[FEATURE REQUEST] - Add Folder (and subfolders) directly

[ricassiocosta]

Is your feature request related to a problem? Please describe.
As a user, I would like to add (encrypt) a entire directory and its subdirectories to the app.

Describe the solution you'd like
In the option Add Video or Image/GIF, add one more option as "Folder", that will encrypt (recursively) one specific folder, keeping the original directory tree.

** Alternative solutions **
Add the "Import Files" button inside each included folder in the app, so we can create subfolders inside this folder and add the files directly to it.

Additional context
This is really handful when you have a plenty of files (already organized by folders) and you want to encrypt them, without the work of creating the folders in the app.

Perhaps rename the title to "import whole Folder (and subfolders)" ?
