weights: increase temporal selection-only (not state) weights (multiply by 10 on each step) until they sum up into large enough number for random selection

Small state weights will be summed into quite small value,
random generator will not be able to produce a value
with enough bits of entropy. In some cases @pos below
will always be zero ending up always selecting the first node.

This simple algorithm increases all weights until they sum up
to the large enough range.
