Port OpenCV.Extra.Tracking to OpenCV-3.3.0

[basvandijk]

The API of the OpenCV tracking module has changed between 3.2.0 and 3.3.0. Building the corresponding Haskell module results in the following errors:

src/OpenCV/Extra/Tracking.cpp: In function ‘Ptr_Tracker* inline_c_OpenCV_Extra_Tracking_0_efe6eac7c3946190981535cdf313473c4fadfc96(const char*)’:

I disabled the module for now so that the rest can be build with OpenCV-3.3.0.

@tolysz do you have an opportunity to look into this?

https://github.com/LumiGuide/haskell-opencv/pull/100 Fixes the compilation, and allows to track objects again.

The basic support is back. The OpenCV library changed the usage a bit. If someone has time, there is a room for converting Trackers into a class (or something) as each tracker takes parameters of a different type. The new tracker uses some big blob so there is a rough edge there.
