Review Comment:
> topicName.replace(".", "_")
I use AWS Glue catalog, which doesn't support nested namespaces. Topic names
with more than 1 `.` would be invalid table names, so one thing we can do is
replace all the `.` characters
The Debezium JDBC sink connector [0] also does this, so it's not totally
unheard of
It probably makes most sense to turn this into it's own config, maybe
something like `iceberg.tables.route-pattern.namespace-separator`?
