Possible error in createExrCamVray.py

[vicnaum]

In vfxpipe/nuke/fxpipenukescripts/createExrCamVray.py:
line 18: reqFields = ['exr/camera%s' % i for i in ('FocalLength', 'Aperture', 'Transform')]

It's checking for "FocalLength" field, but later is working only with camera FOV:
line 51: fov = node.metadata( 'exr/cameraFov', frame) # get camera FOV

There's no "FocalLength" field in vRay 3 for 3ds max 2015 (didn't check earlier).
So this check is redundant and should be checking for 'Fov' instead.
