Allow parsing any permutation of create sequence options

Hi, many thanks for the project!

I would like to be able to parse the create sequence options in any particular order instead of just what postgreslq/duckdb support. Afaik oracle for example allows any permutation of the options.

If this is something that you'd be willing accept, I would be happy to implement the necessary changes to allow any permutation and hide it behind something like a dialect flag.

Start by locating the create-sequence option parser and its existing PostgreSQL/DuckDB ordering handling. Compare the requested Oracle-style permutations and determine how a dialect flag should control them; done means supported permutations parse correctly without changing existing dialect behavior, with tests covering the ordering cases.
