LibVideo: Make probability tables save to the specified index

Browse source 
Previously, saved probability tables were being inserted, causing the
Vector to increase in size when it should say fixed at a size of 4. This
changes the Vector to an Array<T, 4> which will default-initalize and
allow assigning to any index without previously setting size.
