Memory Changes part 2

Browse source 
* Slightly refactors RangeLists from the last Memory Changes MR, which fixes issue 61.

* Convert as many const size array iterators to span iterators as possible. When iterating over a const size array, every iteration created a Span, now only the first iteration does in most places.

* Now using object pooling for a few object types that were rapidly deleted and recreated.

* Converted a few flag checks to binary operations to save memory allocations.
