feat(UnsafeBitSet): refactor iterator to use pointer

Browse Source 
Refactored UnsafeBitSet.Iterator to store a pointer to the bitset and accept a start index in its constructor. Updated GetIterator to support an optional start parameter and return an iterator using a pointer to the current instance. Revised Program.cs to demonstrate new usage and removed unrelated code. Bumped assembly version to 1.6.11.
