fix: correct + call - #61

Previously, whenever one called `+` over more than 2 hypervectors, the operation worked at each pair, that is: a+b+c+d+e = ((((a+b)+c)+d)+e) This behaviour breaks the binary hypervectors because at each step it introduced noise whenever we have a tie. This fix rewrites the `+` overload so it correctly calls the `bundle` function as an array of hypervectors instead of pairwise operations. Added some tests to cover this behaviour.
