SetSlice 0 BinSize bug

SetSlice (Spreads) creates a capital system crash if the slice is set, where BinSize is zero.

in case anybody want to reproduce a nice example:
Input any spread of 4 values, BinSize is 2|0|2, setting slice 0 and 2 works as expected. setting slice 1 freezes my machine.

no problem with GetSlice (Spreads)

fixed that one… hopefully without introducing a new bug.
