Bind serializable Rust data to ODBC statements

The main function of this crate is to use the Serialize trait to automatically make the necessary calls to SQLBindCol and SQLBindParameter. It also supports binding of parameter and row sets, e.g. the following code performs a bulk insert:

#[derive(Clone, Default, Serialize)]
struct Todo {
    id: serde_odbc::Nullable<i32>,
    text: serde_odbc::String<generic_array::typenum::U4096>,
    done: bool,
}

let stmt: serde_odbc::Statement<serde_odbc::ParamSet<Todo>, serde_odbc::NoCols> =
    serde_odbc::Statement::new(&conn, "INSERT INTO todos (id, text, done) VALUES (?, ?, ?)");

stmt.params().reserve(128);
for todo in /* ... */ {
    stmt.params().push(todo);
}

stmt.exec().unwrap();
