[feat] Add commit hook support

[jackd]

Love the package/ecosystem. One piece of functionality I'd love is access to commit hooks.

void *sqlite3_commit_hook(sqlite3*, int(*)(void*), void*);
void *sqlite3_rollback_hook(sqlite3*, void(*)(void *), void*);

If there's interest in supporting it, I could have a stab at putting together a PR based on sqlite3_update_hook

A PR would definitely be welcome! Given that commit and rollback hooks also aren't allowed to modify the database, exposing them as streams similar to how update hook work sounds good to me.

Working on the FFI bindings is a bit complicated and we'd also have to support this for WebAssembly, but if you want to get started on this I'm happy to give pointers or help with code if you get stuck somewhere.
