Julia bindings have createCLAHE but not apply

[csvance]

In Julia its possible to create a CLAHE object but not actually call apply:

using OpenCV
const cv2 = OpenCV

img = UInt8.(round.(255.0*rand(1, 224, 224)))
clahe = cv2.createCLAHE(clipLimit=2.0, tileGridSize=cv2.Size(Int32(4), Int32(4)))
clahe.apply(img)

Results in:

type cv_PtrAllocated has no field apply

Stacktrace:
 [1] getproperty(m::OpenCV.cv_PtrAllocated{OpenCV.CLAHE}, s::Symbol)
   @ OpenCV ~/.julia/artifacts/dcc70861ed0ffc5427898f6aeb436620f33fa02f/OpenCV/src/cv_cxx_wrap.jl:478

Of course Julia doesn't support OOP in the binding so we would need the apply function, but there isn't one in the list of exported functions. Going to look into making a pull request for this.
