add v10 support

[dt-12345]

added support for the main v7 features and reading for up to v10 (I didn't add the v10 non-container root nodes though) wasn't entirely sure how to handle the file nodes (0xa2) so I ended up creating a new struct (also renamed byml::Hash to byml::Dictionary as we have proper hash nodes now) tested on several files from totk and everything seemed to be fine
