Tracking CSRT and MOSSE

[piercus]

Implements CSRT and MOSSE trackers.

This needs to be tested by CI on other opencv build since MOSSE and CSRT are only in OpenCV since 3.4.2 and 3.4.1

@justadudewhohacks Should we test for cv.version.patch > 1 && cv.version.minor > 3 or do we consider cv.version.minor > 3 is enough ?

For now, i'm not able to add psr_threshold into TrackerCSRTParams.h (commented in current version)

I'm getting following error when i uncomment corresponding lines

 CXX(target) Release/obj.target/opencv4nodejs/cc/modules/tracking/Trackers/TrackerCSRT.o

  static FF_GETTER(TrackerCSRTParams, psr_thresholdGet, params.psr_threshold);

I'm not sure if this is related to a specific OpenCV version or if this is related to the implementation.
Any help would be apprecaited, but i think we can merge it anyway.

Thanks for the PR!

Hmm if these trackers have been introduced with a patch version then it would be better yeah. You can simply add the patch version to the cv.version object here.

A quick look in the docs revealed, that psr_threshold has been added with 3.4.4 apparently. Might need a version guard there as well.

Thanks for your feedbacks.

I have added the version checking but also the ci build environments for 3.4.5, 3.4.4 and 3.4.6, and i'm voting to move the default version to 3.4.6, see justadudewhohacks/npm-opencv-build#31

Great! Looks like you made a small typo in trackerParamTests.js:

C:\projects\opencv4nodejs\test\tests\modules\tracking\trackerParamTests.js:75
if(cv.version.minor > 4 || (cv.version.minor === 4 && cv.version.subminor > 3){
^
SyntaxError: Unexpected token {

Ahh didn't notice that one. The docker images do not exist, I have to build them first. For now I would suggest reverting the travis.yml, I will add the CI for the latest builds later on.

Other than that, there still seem to be some buld jobs failing.

@justadudewhohack it's ready now !

Thanks for your help

Great stuff. Thank you!
