How many new positions maximal number may be?
It seems that it is not very much.
Therefore we may don't use clear combinatorical approach
but just build each new position acording roules of
king moving , put it in set and set itself esclude multuples. This is not mathematic but just
context's way. If new positions number too much
and we have TLE we may count mathematically simple
subset as two roork's moving and for rest use set's
approach.
But going this way I have TLE14

Probably it's 16 test
Potentially queen can reach ~3000000 cells, but
many of them coincide. I just choose different from this
I hash 5 byte to 4
