This is the first MAJOR version since v1.0.

The main themes for this big release are:

• add support for Tagging (covering another long-requested feature, Cache Regions)
• add support for a proper Clear
• add support for the new Microsoft HybridCache (abstraction in .NET 9, their impl post .NET 9)
• add specific support for skipping memory/distributed read/write operations
• maybe (stil not 100% sure) a general proper cleanup (eg: removal or error = true) of stuff marked as [Obsolete] for a long time
• maybe (again not 100% sure) a refactoring around the builder, that is now usable only via DI and for which the concrete class is currently internal, to be also directly usable in normal code (eg: new FusionCacheBuilder().WithXyz(...).Build() etc)
