Rewrite SerializationDumper into a more structured library

[paul-griffith]

Currently Java serialized data is parsed through a mangled one-off script generated from the base provided in https://github.com/NickstaDB/SerializationDumper. While the code was rewritten to Java 17, it's still not very ergonomic/practical to use, and should be rewritten to act as more of a 'pure' library, ideally spitting out direct data structures that can then be visualized or parsed down to strings more thoroughly. Unit testing would also be nice. This could be a nice opportunity for a standalone library to exist as a separate project.
