Investigate further inlier ratio w.r.t. GT model and w.r.t estimated model

[johnwlambert]

Currently, the inlier ratio with respect to GT model is greater than that with respect to estimated model for USAC. This is perhaps expected, as the GT should explain the data most appropriately. But our inability to estimate a model with close to as many inliers is unfortunate, and perhaps could be explored further on some representative image pairs.

We see this with USAC on Skydio-8:

However, we do not see this with LORANSAC on Skydio-8
