  1. Fix removeOne for internal set

    Here, in go, if we assign a slice position to a variable, we'll have a copy.
    
    ki.Start = v + 1, on line 218, was just modifying a copy, which is not what was intended to be done here.
    
    If we get the reference as done in the change, we'll modify `ki.Start`properly. Another option would be to reasign the copy to the array position. Either way, this should be fixed.
    
    Simple test which would fail:
    
    func (suite *IIntervalSetTestSuite) TestRemoveOne() {
    	i := NewIntervalSet()
    	i.addInterval(antlr.NewInterval(5, 10))
    
    	i.removeOne(7)
    
    	suite.Len(i.intervals, 2)
    	suite.Equal(5, i.intervals[0].Start)
    	suite.Equal(7, i.intervals[0].Stop)
    	suite.Equal(8, i.intervals[1].Start)
    	suite.Equal(10, i.intervals[1].Stop)
    }
