Existing `get`/`set` logic is flawed in that it doesn't work on Big Endian operating systems, and it allocates heap objects when it doesn't need to. `System.Buffers.Binary.BinaryPrimitives` in the `System.Memory` NuGet package provides both Little Endian and Big Endian methods to read and write data; all the `get`/`set` operations have been reworked to use this new API. This removes the need for PKHeX's manual `BigEndian` class, as all functions are already covered by the BinaryPrimitives API. The `StringConverter` has now been rewritten to accept a Span to read from & write to, no longer requiring a temporary StringBuilder. Other Fixes included: - The Super Training UI for Gen6 has been reworked according to the latest block structure additions. - Cloning a Stadium2 Save File now works correctly (opening from the Folder browser list). - Checksum & Sanity properties removed from parent PKM class, and is now implemented via interface.
