Openni2 does not handle oni files

I am not able to load a oni file (OpenNI record file) with openni2 in Indigo. In Hydro I was able to load it simply with: roslaunch openni2_launch openni2.launch device_id:=/path/to/your/file.oni
but in Indigo openni2 still tries to open the real device. Do you have the same problem?

I'm guessing it is due to this commit: 17c1072 -- in the past it would have probably fallen through and returned the string name, now it returns the empty string -- you could try adding an extra case before the matching attempt which checks if the file ends with .oni and if so, returns the device_id as-is. If that works, we can gladly accept a PR to fix this regression.

It worked! Thanks.
I simply added this to line 682:
```
// check if device_id is a oni file
else if( device_id.size() - device_id.rfind(".oni") == 4 ) {
return device_id;
}

Same issue here, does anyone has a fixed fork?

If you add the above two lines to line 682, it fixes the problem.
I did a pull request on openni2_camera.
