Rework detector API and implement Harris detector

Switch the detector API to a single function which accepts
a float image and detector options. This makes usage of
feature detection more unified across different algorithms.

Options structure is pretty much straightforward and contains
detector to be used and all the detector-specific settings.

Also implemented Harris feature detection algorithm which
is not as fast as FAST one but is expected to detect more
robust feature points. It is also likely that less features
are detected, but better quality than quantity.

Blender will now use Harris detector by default, later we'll
remove FAST detector.

     Also fixed variable shadowing which lead to wrong
     markers positions (were either zero or undefined).

-    Camera intrinsics unit tests fixes
-    
-    - Existing test ApplyIsInvertibleSimple was not
-      doing right thing - distortion model used there
-      was ininvertible.
-    
-      Tweaked parameters in a way model is invertible now.
-    
-    - Added some own tests which tests;
-    
-      * Principal point always maps from pixel space to
-        zero normalized position.
-    
-      * Some basic tests to check whether individual
-        apply/invert works correct.
