Support byte[] in @HollowPrimaryKey for ObjectInternPool in HollowHistoryUI

[PiotrAuguscik]

When loading states with byte[] as the primary key in Hollow, the ObjectInternPool throws an IllegalArgumentException. This issue occurs because the current implementation of ObjectInternPool does not support interning objects of type byte[], which is needed by HollowHistoryUI.

The proposed solution extends the ObjectInternPool functionality to handle byte[] effectively, allowing HollowHistoryUI to intern these objects without errors.

Current implementation throws exception:

Caused by: java.lang.IllegalArgumentException: Cannot intern object of type [B

Hi @PiotrAuguscik , this breaks the build so I reverted the commit, I think it should just be a matter of applying this diff, but i haven't tested it beyond successful build-
