thrust::uniform_int_distribution<uint64_t> exclusively produces multiples of 4096

The thrust::uniform_int_distribution uses uniform_real_distribution under the hood.
However, for 64 bit numbers this means the lower 12 bits are always 0.

For example:
```
int main( int argc, char** argv )
{
thrust::uniform_int_distribution dist;
// thrust::default_random_engine engine{ 0 };
// thrust::taus88 engine{ 0xdeadbeef };
thrust::ranlux48 engine{ 0 };
for( uint64_t i = 0; i < 1e4; i++ )
std::cout << std::hex << dist( engine ) << std::endl;
}
```

will produce 0s in the lower bits for all the thrust random number generators.
