* removes the lifetime from Row * removes MySqlQueryAs, SqliteQueryAs, etc. (no longer needed) * introduce query_scalar * introduce Decode::accepts to allow overriding runtime type checking per-type (replaces TypeInfo::compatible) * introduce Encode::produces to allow overriding the encoded type per-value * adds a lifetime to Arguments (and introduce the HRTB HasArguments) to support zero-copy encoding with SQLite * renames Database::RawBuffer to HasArguments::ArgumentBuffer * introduce Connect::connect_with to provide an ConnectOptions type explicitly to opt-out of connection string parsing * introduce Value and ValueRef traits to allow decoding-deferred extraction of values from Rows * introduce Encode::encode_by_ref and change Encode::encode to take by-value to try and re-use memory where possible * use thiserror to generate sqlx::Error * [!] temporarily removes query logging * [!] temporarily removes transactions
