Closes #12.
Adds
--end <seed>to bound the searched range.SeedIteratortakes an optional upper bound.next()returns an empty optional once the range is used up, the GPU loop breaks on that before dispatching, and the main loop stops once the range has been handed out. Without--endnothing changes.Bounds are compared by distance from the start rather than by absolute position, so a range may cross zero or 2^63.
--endrequires--startand must differ from it.Seeds are handed out in blocks of 2^28, so a range is rounded up to the next block boundary.
"Total seeds checked" overcounts by one block per GPU thread, since each performs a final fetch_add before seeing the empty optional. Left that as is at the moment.
Verified on Windows across both boundaries.
