Serialization Benchmarks

The following serialization operations were ran on various primitives.

byte[] data = new byte[32];
var memory = new MemoryMemory<byte>(data);
Fixed<T>.TryWrite(memory, default, 0L);
Fixed<T>.TryRead(memory, out T value, 0L);
Variable<T>.TryWrite(memory, default, out int bytesWritten, 0L);
Variable<T>.TryRead(memory, out value, out bytesWritten, 0L);
ZigZag<T>.TryWrite(memory, default, out bytesWritten, 0L);
ZigZag<T>.TryRead(memory, out value, out bytesWritten, 0L);
