101 AP algo: do not interpollate precision

Description

COCO 101 point Average Precision algorithm previously interpolated the precision values, causing skew in the precision line.

Now, we're integrating over the max precision value seen up to a given recall level.

I'm merging this PR to develop as we are actively working on integrating mAP into maestro. If we will find any previously unseen bugs, we will just create a new PR in supervision.
