Invalid compression options with Cassandra 5

[To-om]

Cassandra version 5 has been released. Early tests seem to show that only table creation is causing issues. In the compression options, sstable_compression and chunk_length_kb are used here, but they have been deprecated since Cassandra 3 and removed in Cassandra 5. They have been replaced by class and chunk_length_in_kb.

Even though support for Cassandra version 5 is not official yet, replacing these options would make testing this new version easier. Would you like me to create a PR for this?

Yes, if you could submit a PR that'd be great!
