add subdivide option to the RICH hough finder

When dividing the mRICH area into two parts (hits with y>=0 & y<0) and searching for rings with the hough algorithm in both parts separately , side effects occur. This side effects are worst ring recognition & quality in the splitting area.

The option to subdivide is only disabled for the mRICH.
