FOV splitting

[luigiferiani]

• Adding support for fields of view spanning multiple wells of a multi well plate. Square wells are supported, and so are (experimentally) circular wells. In particular, the code was built to work with the Motif multicamera rigs developed by LoopBio Gmbh. I will think of a way to tweak the current solution so that it can be easily adopted by other users.

  • FOV splitting is not enabled by default, but triggered by a parameter.
  • FOV splitting can happen either at the COMPRESS step, or at the features step (see this commit for more information)
  • Both the Viewer and the Summarizer support FOV-splitting-information.

• Added support for OpenCV 4: the signature of cv2.findContours changed in OpenCV >= 4.0.0. Placed checks that deal with the different number of outputs with OpenCV 3.x and 4.x. This should make installation easier for users, since OpenCV had to be forced to be a specific version to avoid this bug.

• Fixed bug in trackProvenance, the version of Tierpsy was not being recorded.

Sorry Avelino, Eleni realised that my version and hers would have conflicts so we'll resolve them on our side and only submit you one PR
