* The Newtonsoft.Json.Bson.BsonDataWriter cannot be used for Guids with `GuidRepresentation.CSharpLegacy`
* because it will always write Guids with with BinaryData subtype `0x04` that map to `BsonBinaryType.Uuid`.
* `BsonBinaryType.OldUuid` would write the required BinaryData subtype (`0x03`), but there is no way to
* force its use through the public API surface (the subtype it is actually hardcoded to `BsonBinaryType.Uuid`
* in the JsonNet codebase).
*
* The MongoDb BSON writer instead use BsonBinarySubType.UuidLegacy (`0x03`) when the type
* is `GuidRepresentation.CSharpLegacy`.
* The BinaryData subtype `0x04` map to `BsonBinarySubType.UuidStandard`, but it cannot be used
* because then the `Guid` bytes are written in network order (BigEndian) introducting more differences.
*
* This code has been modified to use the `BsonWriterAdapter` and to verify that Guids roundtrip
* correctly when using the adapter.
