v2.3.0 Unity 6.7 support

What's Changed

The focus for this release is adding support for Unity 6.7, which is now in Beta.

The main changes for Unity 6.7 support:

• the new "v9" for the Unity Archive format (which will greatly improves patchability when using chunk based compression, e.g. LZ4, LZ4HC).
• multiple changes to the serialized file format
• updated version of UnityFileSystemApi (necessary for loading the new file format)
• Backward compatibility is maintained to read content built by older versions of Unity. Automated tests include reference files with older versions to help ensure ongoing support.

Independent of 6.7 support - the documentation and support for AssetBundle variants has been improved.

Note: This version does not include support for Unity 6.7 Content Directories. The ContentLayout.json is changing between Unity 6.6 and Unity 6.7. Currently there is a git branch with initial support, which will be folded into an upcoming release of UnityDataTools once final schema for 6.7 is set, see #147
