The new BitConverter methods could be useful, and new Vector APIs could make it feasible to implement vectorized ChaCha in a instruction set agnostic manner.

As of .NET 6, Vector<T> does not include shift operators, so we can't use it to implement ChaCha efficiently yet. However, support has been merged so the next version of .NET should support this. Shuffling may also be necessary to meet performance requirements.

We were able to use new floating point APIs in ba17a5b to do bitwise convertion between floats and integers - we may not need unsafe in Core when targeting .NET 6 now.
