feat: remove ensureDir

The current implementation was broken (it did not always close dir handlers).

Removing this method also permit us to remove the following dependencies:
- Babel 5 (very old and unmaintained)
- Bluebird

-Ensures that the directory exists. If the directory structure does not exist, it is created.
-
-Example:
-
-```javascript
-smb2Client.ensureDir('path\\to\\directory', function(err) {
-  if (err) throw err;
-  console.log('directory structure has been created');
-});
-```
-
 > `smb2Client.exists ( path, callback )`
 
 Test whether or not the given path exists by checking with the file system.
