Performance Profiling and Improvement

[robrua]

The main design concerns while developing Orianna were usability-focused. While some attempt was made to minimize resource usage with things like memoized suppliers in core types, Orianna is probably currently more resource-hungry than it needs to be.

This is a call for contributors to help out in evaluating how the memory and computation performance of Orianna can be optimized while maintaining the usability-focused features the library provides.
