Documentation copied from rusqlite is wrong

E.g. https://github.com/wangfenjin/duckdb-rs/blob/main/src/types/mod.rs

Duckdb uses distinct integer types.

yes, thanks for point out. Still working on the types as actually duckdb is static typing but sqlite is dynamic, they are totally different.

contribute are welcomed!
