Create a table in `db` with name `table_name`, according to `schema`, which is a set of column names and types, constructed like `Tables.Schema(names, types)`
where `names` can be a vector or tuple of String/Symbol column names, and `types` is a vector or tuple of sqlite-compatible types (`Int`, `Float64`, `String`, or unions of `Missing`).
