Remove selections of IR points outside the frame

[willettk]

A few hundred points (<0.03% of total) are somehow recorded as being outside of the 424x424 bounding box of the IR counterpart. Eg,

...
"ir" : {
                "0" : {
                    "x" : "-48.5",
                    "y" : "391.5299987792969"
                },
                "1" : {
                    "x" : "-48.5",
                    "y" : "391.5299987792969"
                },
                "2" : {
                    "x" : "-48.5",
                    "y" : "391.5299987792969"
                }
            }
...

There aren't any obvious similarities in user, subject, survey, operating system, date, physical location of subject, or position with regard to the bounding box.

Needs something in the code to automatically remove these points from consideration.

Same applies to (just a few) radio points as well.
