MarcWils.PerfCopy (nuget): Extension methods providing high performance deep copy capability for of arrays of common value types - currently: byte, char, short, int, long, and their unsigned brethren where applicable. Considerably faster than Array.Copy - and it's also faster than Buffer.BlockCopy in most situations!  High-performance enabled through use of optimised 'unsafe' blocks. This package could be a good addition to other packages if you're building in copying of some kind that would benefit from being fast.  This is the same codebase as the PerfCopy NuGet package from https://github.com/xorxornop/PerfCopy. Only the package is converted to support .NET Standard.
