Feature Changes

Improved usability of the EnumBitfield class:
- Allow the class to be created directly from the base type. This simplifies cases where the bitfield is serialised and then restored.
- Allow the class to receive assignment from the base type. This is mostly for symmetry with the other assignment operator.
Removes unused headers to streamline inclusion and reduce build times.
Updates the ASSERT macro implementation to use std::array instead of C-style arrays for better safety.
Functors passed in to the string functions no longer use universal references. This is in conformance with the STL.
Update all SDKs to their latest released versions.
