Adding a version of unaligned copy for little-endian platforms that provides a single abstraction for vectorized unaligned copy. This replaces the v0 BitStream + unalignedCopy abstractions making a v1 "bit stream" into simply an std::vector and a std::size_t bit_offset. The abstraction allows the vector's word size to be parameterized which could provide better optimizations where a given architecture can perform single operations across multiple bytes instead of hard-coding all 8-bit operations. The usefulness versus complexity of this optimization will play out in subsequent pull-requests as we start utilizing this copy operation in the generated dsdl types.

Progress on OpenCyphal-Garage#235, adding unaligned copy Version 2 of this utility. This one is endian agnostic (I think).

This is a placeholder. Hopefully I can break this down into several/many tasks before starting on the Alpha milestone.
